+ * This test class validates that the Spring Boot auto-configuration for MCP clients works + * correctly, including bean creation, property binding, and customization support. The + * tests focus on verifying that the auto-configuration creates the expected beans without + * requiring actual MCP protocol communication. + * + *

Key Testing Patterns:

+ *
    + *
  • Mock Transport Configuration: Uses properly configured Mockito + * mocks for {@code McpClientTransport} that handle default interface methods like + * {@code protocolVersions()}, {@code connect()}, and {@code sendMessage()}
    • + * + *
  • Initialization Prevention: Most tests use + * {@code spring.ai.mcp.client.initialized=false} to prevent the auto-configuration from + * calling {@code client.initialize()} explicitly, which would cause 20-second timeouts + * waiting for real MCP protocol communication
    • + * + *
  • Bean Creation Testing: Tests verify that the correct beans are + * created (e.g., {@code mcpSyncClients}, {@code mcpAsyncClients}) without requiring full + * client initialization
    • + *
+ * + *

Important Notes:

+ *
    + *
  • When {@code initialized=false} is used, the {@code toolCallbacks} bean is not + * created because it depends on fully initialized MCP clients
    • + * + *
  • The mock transport configuration is critical - Mockito mocks don't inherit default + * interface methods, so {@code protocolVersions()}, {@code connect()}, and + * {@code sendMessage()} must be explicitly configured
    • + * + *
  • Tests validate both the auto-configuration behavior and the resulting + * {@code McpClientCommonProperties} configuration

    - * This configuration class sets up the core MCP server components with support for both - * synchronous and asynchronous operation modes. The server type is controlled through the - * {@code spring.ai.mcp.server.type} property, defaulting to SYNC mode. - *

    - * Core features and capabilities include: - *

      - *
    • Tools: Extensible tool registration system supporting both sync and async - * execution
      • - *
    • Resources: Static and dynamic resource management with optional change - * notifications
      • - *
    • Prompts: Configurable prompt templates with change notification support
      • - *
    • Transport: Flexible transport layer with built-in support for: - *
        - *
      • STDIO (default): Standard input/output based communication
        • - *
      • WebMvc: HTTP-based transport when Spring MVC is available
        • - *
      • WebFlux: Reactive transport when Spring WebFlux is available
        • - *
      - *
      • - *
    - *

    - * The configuration is activated when: - *

      - *
    • The required MCP classes ({@link McpSchema} and {@link McpSyncServer}) are on the - * classpath
      • - *
    • The {@code spring.ai.mcp.server.enabled} property is true (default)
      • - *
    - *

    - * Server configuration is managed through {@link McpServerProperties} with support for: - *

      - *
    • Server identification (name, version)
      • - *
    • Transport selection
      • - *
    • Change notification settings for tools, resources, and prompts
      • - *
    • Sync/Async operation mode selection
      • - *
    - *

+# Migration Guide: Spring AI Google GenAI Autoconfiguration
+
+## Overview
+
+This guide helps you migrate from the old Vertex AI-based autoconfiguration to the new Google GenAI SDK-based autoconfiguration.
+
+## Key Changes
+
+### 1. Property Namespace Changes
+
+Old properties:
+```properties
+spring.ai.vertex.ai.gemini.project-id=my-project
+spring.ai.vertex.ai.gemini.location=us-central1
+spring.ai.vertex.ai.gemini.chat.options.model=gemini-pro
+spring.ai.vertex.ai.embedding.text.options.model=textembedding-gecko
+```
+
+New properties:
+```properties
+# For Vertex AI mode
+spring.ai.google.genai.project-id=my-project
+spring.ai.google.genai.location=us-central1
+spring.ai.google.genai.chat.options.model=gemini-2.0-flash
+
+# For Gemini Developer API mode (new!)
+spring.ai.google.genai.api-key=your-api-key
+spring.ai.google.genai.chat.options.model=gemini-2.0-flash
+
+# Embedding properties
+spring.ai.google.genai.embedding.project-id=my-project
+spring.ai.google.genai.embedding.location=us-central1
+spring.ai.google.genai.embedding.text.options.model=text-embedding-004
+```
+
+### 2. New Authentication Options
+
+The new SDK supports both:
+- **Vertex AI mode**: Using Google Cloud credentials (same as before)
+- **Gemini Developer API mode**: Using API keys (new!)
+
+### 3. Removed Features
+
+- `transport` property is no longer needed
+- Multimodal embedding autoconfiguration has been removed (pending support in new SDK)
+
+### 4. Bean Name Changes
+
+If you were autowiring beans by name:
+- `vertexAi` → `googleGenAiClient`
+- `vertexAiGeminiChat` → `googleGenAiChatModel`
+- `textEmbedding` → `googleGenAiTextEmbedding`
+
+### 5. Class Changes
+
+If you were importing classes directly:
+- `com.google.cloud.vertexai.VertexAI` → `com.google.genai.Client`
+- `org.springframework.ai.vertexai.gemini.*` → `org.springframework.ai.google.genai.*`
+
+## Migration Steps
+
+1. Update your application properties:
+   - Replace `spring.ai.vertex.ai.*` with `spring.ai.google.genai.*`
+   - Remove any `transport` configuration
+
+2. If using API key authentication:
+   - Set `spring.ai.google.genai.api-key` property
+   - Remove project-id and location for chat (not needed with API key)
+
+3. Update any custom configurations or bean references
+
+4. Test your application thoroughly
+
+## Environment Variables
+```bash
+export GOOGLE_CLOUD_PROJECT=my-project
+export GOOGLE_CLOUD_LOCATION=us-central1
+```
+
+New (additional option):
+```bash
+export GOOGLE_API_KEY=your-api-key
+```
+
+## Backward Compatibility
+
+The old autoconfiguration module is still available but deprecated. We recommend migrating to the new module as soon as possible.

+# Google Gen AI Embeddings module
+
+Please note that at this time the *spring-ai-google-genai-embedding* module supports only text embeddings only.
+
+This is due to the fact that the Google GenAI SDK supports text embeddings only, with multimedia embeddings pending.

+/**
+ * Google GenAI Chat Model implementation that provides access to Google's Gemini language
+ * models.
+ *
+ * 
    
+ * Key features include:
+ * 
      
+ * 
    • Support for multiple Gemini model versions including Gemini Pro, Gemini 1.5 Pro,
+ * Gemini 1.5/2.0 Flash variants
      • 
+ * 
    • Tool/Function calling capabilities through {@link ToolCallingManager}
      • 
+ * 
    • Streaming support via {@link #stream(Prompt)} method
      • 
+ * 
    • Configurable safety settings through {@link GoogleGenAiSafetySetting}
      • 
+ * 
    • Support for system messages and multi-modal content (text and images)
      • 
+ * 
    • Built-in retry mechanism and observability through Micrometer
      • 
+ * 
    • Google Search Retrieval integration
      • 
+ * 
    
+ *
+ * 
    
+ * The model can be configured with various options including temperature, top-k, top-p
+ * sampling, maximum output tokens, and candidate count through
+ * {@link GoogleGenAiChatOptions}.
+ *
+ * 
    
+ * Use the {@link Builder} to create instances with custom configurations:
+ *
+ * 
    {@code
+ * GoogleGenAiChatModel model = GoogleGenAiChatModel.builder()
+ * 		.genAiClient(genAiClient)
+ * 		.defaultOptions(options)
+ * 		.toolCallingManager(toolManager)
+ * 		.build();

+. Create an ElevenLabs account and obtain an API key.  You can sign up at the https://elevenlabs.io/sign-up[ElevenLabs signup page]. Your API key can be found on your profile page after logging in.
+. Add the `spring-ai-elevenlabs` dependency to your project's build file.  For more information, refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section.
+
+== Auto-configuration
+
+Spring AI provides Spring Boot auto-configuration for the ElevenLabs Text-to-Speech Client.
+To enable it, add the following dependency to your project's Maven `pom.xml` file:
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-starter-model-elevenlabs
+
+----
+
+or to your Gradle `build.gradle` build file:
+
+[source,groovy]
+----
+dependencies {
+    implementation 'org.springframework.ai:spring-ai-starter-model-elevenlabs'
+}
+----
+
+TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.
+
+== Speech Properties
+
+=== Connection Properties
+
+The prefix `spring.ai.elevenlabs` is used as the property prefix for *all* ElevenLabs related configurations (both connection and TTS specific settings).  This is defined in `ElevenLabsConnectionProperties`.
+
+[cols="3,5,1"]
+|====
+| Property | Description | Default
+| spring.ai.elevenlabs.base-url | The base URL for the ElevenLabs API. | https://api.elevenlabs.io
+| spring.ai.elevenlabs.api-key  | Your ElevenLabs API key.           | -
+|====
+
+=== Configuration Properties
+
+The prefix `spring.ai.elevenlabs.tts` is used as the property prefix to configure the ElevenLabs Text-to-Speech client, specifically. This is defined in `ElevenLabsSpeechProperties`.
+
+[cols="3,5,2"]
+|====
+| Property | Description | Default
+
+| spring.ai.elevenlabs.tts.options.model-id | The ID of the model to use. | eleven_turbo_v2_5
+| spring.ai.elevenlabs.tts.options.voice-id | The ID of the voice to use.  This is the *voice ID*, not the voice name. | 9BWtsMINqrJLrRacOk9x
+| spring.ai.elevenlabs.tts.options.output-format |  The output format for the generated audio. See xref:#output-formats[Output Formats] below. | mp3_22050_32
+| spring.ai.elevenlabs.tts.enabled | Enable or disable the ElevenLabs Text-to-Speech client. | true
+|====
+
+NOTE: The base URL and API key can also be configured *specifically* for TTS using `spring.ai.elevenlabs.tts.base-url` and `spring.ai.elevenlabs.tts.api-key`. However, it is generally recommended to use the global `spring.ai.elevenlabs` prefix for simplicity, unless you have a specific reason to use different credentials for different ElevenLabs services. The more specific `tts` properties will override the global ones.
+
+TIP: All properties prefixed with `spring.ai.elevenlabs.tts.options` can be overridden at runtime.

+
+
+== Runtime Options [[speech-options]]
+
+The `ElevenLabsTextToSpeechOptions` class provides options to use when making a text-to-speech request.  On start-up, the options specified by `spring.ai.elevenlabs.tts` are used, but you can override these at runtime.  The following options are available:
+
+* `modelId`: The ID of the model to use.
+* `voiceId`: The ID of the voice to use.
+* `outputFormat`: The output format of the generated audio.
+* `voiceSettings`:  An object containing voice settings such as `stability`, `similarityBoost`, `style`, `useSpeakerBoost`, and `speed`.
+* `enableLogging`: A boolean to enable or disable logging.
+* `languageCode`: The language code of the input text (e.g., "en" for English).
+* `pronunciationDictionaryLocators`:  A list of pronunciation dictionary locators.
+* `seed`: A seed for random number generation, for reproducibility.
+* `previousText`: Text before the main text, for context in multi-turn conversations.
+* `nextText`: Text after the main text, for context in multi-turn conversations.
+* `previousRequestIds`: Request IDs from previous turns in a conversation.
+* `nextRequestIds`: Request IDs for subsequent turns in a conversation.
+* `applyTextNormalization`:  Apply text normalization ("auto", "on", or "off").
+* `applyLanguageTextNormalization`:  Apply language text normalization.
+
+For example:
+
+[source,java]
+----
+ElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder()
+    .model("eleven_multilingual_v2")
+    .voiceId("your_voice_id")
+    .outputFormat(ElevenLabsApi.OutputFormat.MP3_44100_128.getValue())
+    .build();
+
+TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example.", speechOptions);
+TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);
+----
+
+=== Using Voice Settings
+
+You can customize the voice output by providing `VoiceSettings` in the options. This allows you to control properties like stability and similarity.
+
+[source,java]
+----
+var voiceSettings = new ElevenLabsApi.SpeechRequest.VoiceSettings(0.75f, 0.75f, 0.0f, true);
+
+ElevenLabsTextToSpeechOptions speechOptions = ElevenLabsTextToSpeechOptions.builder()
+    .model("eleven_multilingual_v2")
+    .voiceId("your_voice_id")
+    .voiceSettings(voiceSettings)
+    .build();
+
+TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("This is a test with custom voice settings!", speechOptions);
+TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);
+----
+
+== Manual Configuration
+
+Add the `spring-ai-elevenlabs` dependency to your project's Maven `pom.xml` file:
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-elevenlabs
+
+----
+
+or to your Gradle `build.gradle` build file:
+
+[source,groovy]
+----
+dependencies {
+    implementation 'org.springframework.ai:spring-ai-elevenlabs'
+}
+----
+
+TIP: Refer to the xref:getting-started.adoc#dependency-management[Dependency Management] section to add the Spring AI BOM to your build file.
+
+Next, create an `ElevenLabsTextToSpeechModel`:
+
+[source,java]
+----
+ElevenLabsApi elevenLabsApi = ElevenLabsApi.builder()
+		.apiKey(System.getenv("ELEVEN_LABS_API_KEY"))
+		.build();
+
+ElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder()
+	.elevenLabsApi(elevenLabsApi)
+	.defaultOptions(ElevenLabsTextToSpeechOptions.builder()
+		.model("eleven_turbo_v2_5")
+		.voiceId("your_voice_id") // e.g. "9BWtsMINqrJLrRacOk9x"
+		.outputFormat("mp3_44100_128")
+		.build())
+	.build();
+
+// The call will use the default options configured above.
+TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Hello, this is a text-to-speech example.");
+TextToSpeechResponse response = elevenLabsTextToSpeechModel.call(speechPrompt);
+
+byte[] responseAsBytes = response.getResult().getOutput();
+----
+
+== Streaming Real-time Audio
+
+The ElevenLabs Speech API supports real-time audio streaming using chunk transfer encoding.  This allows audio playback to begin before the entire audio file is generated.
+
+[source,java]
+----
+ElevenLabsApi elevenLabsApi = ElevenLabsApi.builder()
+		.apiKey(System.getenv("ELEVEN_LABS_API_KEY"))
+		.build();
+
+ElevenLabsTextToSpeechModel elevenLabsTextToSpeechModel = ElevenLabsTextToSpeechModel.builder()
+	.elevenLabsApi(elevenLabsApi)
+	.build();
+
+ElevenLabsTextToSpeechOptions streamingOptions = ElevenLabsTextToSpeechOptions.builder()
+    .model("eleven_turbo_v2_5")
+    .voiceId("your_voice_id")
+    .outputFormat("mp3_44100_128")
+    .build();
+
+TextToSpeechPrompt speechPrompt = new TextToSpeechPrompt("Today is a wonderful day to build something people love!", streamingOptions);
+
+Flux responseStream = elevenLabsTextToSpeechModel.stream(speechPrompt);
+
+// Process the stream, e.g., play the audio chunks
+responseStream.subscribe(speechResponse -> {
+    byte[] audioChunk = speechResponse.getResult().getOutput();
+    // Play the audioChunk
+});
+
+----
+
+== Voices API
+
+The ElevenLabs Voices API allows you to retrieve information about available voices, their settings, and default voice settings. You can use this API to discover the `voiceId`s to use in your speech requests.
+
+To use the Voices API, you'll need to create an instance of `ElevenLabsVoicesApi`:
+
+[source,java]
+----
+ElevenLabsVoicesApi voicesApi = ElevenLabsVoicesApi.builder()
+        .apiKey(System.getenv("ELEVEN_LABS_API_KEY"))
+        .build();
+----
+
+You can then use the following methods:
+
+*   `getVoices()`: Retrieves a list of all available voices.
+*   `getDefaultVoiceSettings()`: Gets the default settings for voices.
+*   `getVoiceSettings(String voiceId)`: Returns the settings for a specific voice.
+*   `getVoice(String voiceId)`: Returns metadata about a specific voice.
+
+Example:
+
+[source,java]
+----
+// Get all voices
+ResponseEntity voicesResponse = voicesApi.getVoices();
+List voices = voicesResponse.getBody().voices();
+
+// Get default voice settings
+ResponseEntity defaultSettingsResponse = voicesApi.getDefaultVoiceSettings();
+ElevenLabsVoicesApi.VoiceSettings defaultSettings = defaultSettingsResponse.getBody();
+
+// Get settings for a specific voice
+ResponseEntity voiceSettingsResponse = voicesApi.getVoiceSettings(voiceId);
+ElevenLabsVoicesApi.VoiceSettings voiceSettings = voiceSettingsResponse.getBody();
+
+// Get details for a specific voice
+ResponseEntity voiceDetailsResponse = voicesApi.getVoice(voiceId);
+ElevenLabsVoicesApi.Voice voiceDetails = voiceDetailsResponse.getBody();
+----
+
+== Example Code

+
+== Thinking
+
+Anthropic Claude models support a "thinking" feature that allows the model to show its reasoning process before providing a final answer. This feature enables more transparent and detailed problem-solving, particularly for complex questions that require step-by-step reasoning.
+
+[NOTE]
+====
+*Supported Models*
+
+The thinking feature is supported by the following Claude models:
+
+* Claude 4 models (`claude-opus-4-20250514`, `claude-sonnet-4-20250514`)
+* Claude 3.7 Sonnet (`claude-3-7-sonnet-20250219`)
+
+*Model capabilities:*
+
+* *Claude 3.7 Sonnet*: Returns full thinking output. Behavior is consistent but does not support summarized or interleaved thinking.
+* *Claude 4 models*: Support summarized thinking, interleaved thinking, and enhanced tool integration.
+
+API request structure is the same across all supported models, but output behavior varies.
+====
+
+=== Thinking Configuration
+
+To enable thinking on any supported Claude model, include the following configuration in your request:
+
+==== Required Configuration
+
+1. **Add the `thinking` object**:
+- `"type": "enabled"`
+- `budget_tokens`: Token limit for reasoning (recommend starting at 1024)
+
+2. **Token budget rules**:
+- `budget_tokens` must typically be less than `max_tokens`
+- Claude may use fewer tokens than allocated
+- Larger budgets increase depth of reasoning but may impact latency
+- When using tool use with interleaved thinking (Claude 4 only), this constraint is relaxed, but not yet supported in Spring AI.
+
+==== Key Considerations
+
+* **Claude 3.7** returns full thinking content in the response
+* **Claude 4** returns a *summarized* version of the model's internal reasoning to reduce latency and protect sensitive content
+* **Thinking tokens are billable** as part of output tokens (even if not all are visible in response)
+* **Interleaved Thinking** is only available on Claude 4 models and requires the beta header `interleaved-thinking-2025-05-14`
+
+==== Tool Integration and Interleaved Thinking
+
+Claude 4 models support interleaved thinking with tool use, allowing the model to reason between tool calls.
+
+[NOTE]
+====
+The current Spring AI implementation supports basic thinking and tool use separately, but does not yet support interleaved thinking with tool use (where thinking continues across multiple tool calls).
+====
+
+For details on interleaved thinking with tool use, see the https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#extended-thinking-with-tool-use[Anthropic documentation].
+
+=== Non-streaming Example
+
+Here's how to enable thinking in a non-streaming request using the ChatClient API:
+
+[source,java]
+----
+ChatClient chatClient = ChatClient.create(chatModel);
+
+// For Claude 3.7 Sonnet - explicit thinking configuration required
+ChatResponse response = chatClient.prompt()
+    .options(AnthropicChatOptions.builder()
+        .model("claude-3-7-sonnet-latest")
+        .temperature(1.0)  // Temperature should be set to 1 when thinking is enabled
+        .maxTokens(8192)
+        .thinking(AnthropicApi.ThinkingType.ENABLED, 2048)  // Must be ≥1024 && < max_tokens
+        .build())
+    .user("Are there an infinite number of prime numbers such that n mod 4 == 3?")
+    .call()
+    .chatResponse();
+
+// For Claude 4 models - thinking is enabled by default
+ChatResponse response4 = chatClient.prompt()
+    .options(AnthropicChatOptions.builder()
+        .model("claude-opus-4-0")
+        .maxTokens(8192)
+        // No explicit thinking configuration needed
+        .build())
+    .user("Are there an infinite number of prime numbers such that n mod 4 == 3?")
+    .call()
+    .chatResponse();
+
+// Process the response which may contain thinking content
+for (Generation generation : response.getResults()) {
+    AssistantMessage message = generation.getOutput();
+    if (message.getText() != null) {
+        // Regular text response
+        System.out.println("Text response: " + message.getText());
+    }
+    else if (message.getMetadata().containsKey("signature")) {
+        // Thinking content
+        System.out.println("Thinking: " + message.getMetadata().get("thinking"));
+        System.out.println("Signature: " + message.getMetadata().get("signature"));
+    }
+}
+----
+
+=== Streaming Example
+
+You can also use thinking with streaming responses:
+
+[source,java]
+----
+ChatClient chatClient = ChatClient.create(chatModel);
+
+// For Claude 3.7 Sonnet - explicit thinking configuration
+Flux responseFlux = chatClient.prompt()
+    .options(AnthropicChatOptions.builder()
+        .model("claude-3-7-sonnet-latest")
+        .temperature(1.0)
+        .maxTokens(8192)
+        .thinking(AnthropicApi.ThinkingType.ENABLED, 2048)
+        .build())
+    .user("Are there an infinite number of prime numbers such that n mod 4 == 3?")
+    .stream();
+
+// For Claude 4 models - thinking is enabled by default
+Flux responseFlux4 = chatClient.prompt()
+    .options(AnthropicChatOptions.builder()
+        .model("claude-opus-4-0")
+        .maxTokens(8192)
+        // No explicit thinking configuration needed
+        .build())
+    .user("Are there an infinite number of prime numbers such that n mod 4 == 3?")
+    .stream();
+
+// For streaming, you might want to collect just the text responses
+String textContent = responseFlux.collectList()
+    .block()
+    .stream()
+    .map(ChatResponse::getResults)
+    .flatMap(List::stream)
+    .map(Generation::getOutput)
+    .map(AssistantMessage::getText)
+    .filter(text -> text != null && !text.isBlank())
+    .collect(Collectors.joining());
+----
+
+=== Tool Use Integration
+
+Claude 4 models integrate thinking and tool use capabilities:
+
+* *Claude 3.7 Sonnet*: Supports both thinking and tool use, but they operate separately and require more explicit configuration
+* *Claude 4 models*: Natively interleave thinking and tool use, providing deeper reasoning during tool interactions
+
+=== Benefits of Using Thinking
+
+The thinking feature provides several benefits:
+
+1. **Transparency**: See the model's reasoning process and how it arrived at its conclusion
+2. **Debugging**: Identify where the model might be making logical errors
+3. **Education**: Use the step-by-step reasoning as a teaching tool
+4. **Complex Problem Solving**: Better results on math, logic, and reasoning tasks
+
+Note that enabling thinking requires a higher token budget, as the thinking process itself consumes tokens from your allocation.

+(o1, o3, o4-mini series)

+
+IMPORTANT: The parameters `maxTokens` and `maxCompletionTokens` are **mutually exclusive**. Setting both parameters simultaneously will result in an API error from Azure OpenAI. The Spring AI Azure OpenAI client will automatically clear the previously set parameter when you set the other one, with a warning message.

+[NOTE]
+====
+When using GPT-5 models such as `gpt-5`, `gpt-5-mini`, and `gpt-5-nano`, the `temperature` parameter is not supported.
+These models are optimized for reasoning and do not use temperature.
+Specifying a temperature value will result in an error.
+In contrast, conversational models like `gpt-5-chat` do support the `temperature` parameter.
+====
+
 NOTE: You can override the common `spring.ai.openai.base-url` and `spring.ai.openai.api-key` for the `ChatModel` and `EmbeddingModel` implementations.
 The `spring.ai.openai.chat.base-url` and `spring.ai.openai.chat.api-key` properties, if set, take precedence over the common properties.
 This is useful if you want to use different OpenAI accounts for different models and different model endpoints.
 
 TIP: All properties prefixed with `spring.ai.openai.chat.options` can be overridden at runtime by adding request-specific <> to the `Prompt` call.
 
+=== Token Limit Parameters: Model-Specific Usage
+
+OpenAI provides two mutually exclusive parameters for controlling token generation limits:
+
+[cols="2,3,3", stripes=even]
+|====
+| Parameter | Use Case | Compatible Models
+
+| `maxTokens` | Non-reasoning models | gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-3.5-turbo
+| `maxCompletionTokens` | Reasoning models | o1, o1-mini, o1-preview, o3, o4-mini series
+|====
+
+IMPORTANT: These parameters are **mutually exclusive**. Setting both will result in an API error from OpenAI.
+
+==== Usage Examples
+
+**For non-reasoning models (gpt-4o, gpt-3.5-turbo):**
+[source,java]
+----
+ChatResponse response = chatModel.call(
+    new Prompt(
+        "Explain quantum computing in simple terms.",
+        OpenAiChatOptions.builder()
+            .model("gpt-4o")
+            .maxTokens(150)  // Use maxTokens for non-reasoning models
+        .build()
+    ));
+----
+
+**For reasoning models (o1, o3 series):**
+[source,java]
+----
+ChatResponse response = chatModel.call(
+    new Prompt(
+        "Solve this complex math problem step by step: ...",
+        OpenAiChatOptions.builder()
+            .model("o1-preview")
+            .maxCompletionTokens(1000)  // Use maxCompletionTokens for reasoning models
+        .build()
+    ));
+----
+
+**Builder Pattern Validation:**
+The OpenAI ChatOptions builder automatically enforces mutual exclusivity with a "last-set-wins" approach:
+
+[source,java]
+----
+// This will automatically clear maxTokens and use maxCompletionTokens
+OpenAiChatOptions options = OpenAiChatOptions.builder()
+    .maxTokens(100)           // Set first
+    .maxCompletionTokens(200) // This clears maxTokens and logs a warning
+    .build();
+
+// Result: maxTokens = null, maxCompletionTokens = 200

+== Message Metadata
+
+The ChatClient supports adding metadata to both user and system messages.
+Metadata provides additional context and information about messages that can be used by the AI model or downstream processing.
+
+=== Adding Metadata to User Messages
+
+You can add metadata to user messages using the `metadata()` methods:
+
+[source,java]
+----
+// Adding individual metadata key-value pairs
+String response = chatClient.prompt()
+    .user(u -> u.text("What's the weather like?")
+        .metadata("messageId", "msg-123")
+        .metadata("userId", "user-456")
+        .metadata("priority", "high"))
+    .call()
+    .content();
+
+// Adding multiple metadata entries at once
+Map userMetadata = Map.of(
+    "messageId", "msg-123",
+    "userId", "user-456",
+    "timestamp", System.currentTimeMillis()
+);
+
+String response = chatClient.prompt()
+    .user(u -> u.text("What's the weather like?")
+        .metadata(userMetadata))
+    .call()
+    .content();
+----
+
+=== Adding Metadata to System Messages
+
+Similarly, you can add metadata to system messages:
+
+[source,java]
+----
+// Adding metadata to system messages
+String response = chatClient.prompt()
+    .system(s -> s.text("You are a helpful assistant.")
+        .metadata("version", "1.0")
+        .metadata("model", "gpt-4"))
+    .user("Tell me a joke")
+    .call()
+    .content();
+----
+
+=== Default Metadata Support
+
+You can also configure default metadata at the ChatClient builder level:
+
+[source,java]
+----
+@Configuration
+class Config {
+    @Bean
+    ChatClient chatClient(ChatClient.Builder builder) {
+        return builder
+            .defaultSystem(s -> s.text("You are a helpful assistant")
+                .metadata("assistantType", "general")
+                .metadata("version", "1.0"))
+            .defaultUser(u -> u.text("Default user context")
+                .metadata("sessionId", "default-session"))
+            .build();
+    }
+}
+----
+
+=== Metadata Validation
+
+The ChatClient validates metadata to ensure data integrity:
+
+* Metadata keys cannot be null or empty
+* Metadata values cannot be null
+* When passing a Map, neither keys nor values can contain null elements
+
+[source,java]
+----
+// This will throw an IllegalArgumentException
+chatClient.prompt()
+    .user(u -> u.text("Hello")
+        .metadata(null, "value"))  // Invalid: null key
+    .call()
+    .content();
+
+// This will also throw an IllegalArgumentException
+chatClient.prompt()
+    .user(u -> u.text("Hello")
+        .metadata("key", null))    // Invalid: null value
+    .call()
+    .content();
+----
+
+=== Accessing Metadata
+
+The metadata is included in the generated UserMessage and SystemMessage objects and can be accessed through the message's `getMetadata()` method.
+This is particularly useful when processing messages in advisors or when examining the conversation history.

-`MessageWindowChatMemory` is a chat memory implementation that maintains a window of messages up to a specified maximum size (default: 20 messages).

+= MCP Client Annotations
+
+The MCP Client Annotations provide a declarative way to implement MCP client handlers using Java annotations. 
+These annotations simplify the handling of server notifications and client-side operations.
+
+[IMPORTANT]
+**All MCP client annotations MUST include a `clients` parameter** to associate the handler with a specific MCP client connection. The `clients` must match the connection name configured in your application properties.
+
+== Client Annotations
+
+=== @McpLogging
+
+The `@McpLogging` annotation handles logging message notifications from MCP servers.
+
+==== Basic Usage
+

+public class LoggingHandler {
+
+    @McpLogging(clients = "my-mcp-server")
+    public void handleLoggingMessage(LoggingMessageNotification notification) {
+        System.out.println("Received log: " + notification.level() + 
+                          " - " + notification.data());
+    }
+}

+        })
+        .then();
+}
+----
+
+== Spring Boot Integration
+
+With Spring Boot auto-configuration, client handlers are automatically detected and registered:
+
+[source,java]
+----
+@SpringBootApplication
+public class McpClientApplication {
+    public static void main(String[] args) {
+        SpringApplication.run(McpClientApplication.class, args);
+    }
+}
+
+@Component
+public class MyClientHandlers {
+
+    @McpLogging(clients = "my-server")
+    public void handleLogs(LoggingMessageNotification notification) {
+        // Handle logs
+    }
+
+    @McpSampling(clients = "my-server")
+    public CreateMessageResult handleSampling(CreateMessageRequest request) {
+        // Handle sampling
+    }
+
+    @McpProgress(clients = "my-server")
+    public void handleProgress(ProgressNotification notification) {
+        // Handle progress
+    }
+}
+----
+
+The auto-configuration will:
+
+1. Scan for beans with MCP client annotations
+2. Create appropriate specifications
+3. Register them with the MCP client
+4. Support both sync and async implementations
+5. Handle multiple clients with client-specific handlers
+
+== Configuration Properties
+
+Configure the client annotation scanner and client connections:
+
+[source,yaml]
+----
+spring:
+  ai:
+    mcp:
+      client:
+        type: SYNC  # or ASYNC
+        annotation-scanner:
+          enabled: true
+        # Configure client connections - the connection names become clients values
+        sse:
+          connections:
+            my-server:  # This becomes the clients
+              url: http://localhost:8080
+            tool-server:  # Another clients
+              url: http://localhost:8081
+        stdio:
+          connections:
+            local-server:  # This becomes the clients
+              command: /path/to/mcp-server
+              args:
+                - --mode=production
+----
+
+[IMPORTANT]
+The `clients` parameter in annotations must match the connection names defined in your configuration. In the example above, valid `clients` values would be: `"my-server"`, `"tool-server"`, and `"local-server"`.
+
+== Usage with MCP Client
+
+The annotated handlers are automatically integrated with the MCP client:
+
+[source,java]
+----
+@Autowired
+private List mcpClients;
+
+// The clients will automatically use your annotated handlers based on clients
+// No manual registration needed - handlers are matched to clients by name
+----
+
+For each MCP client connection, handlers with matching `clients` will be automatically registered and invoked when the corresponding events occur.

+        String responseWithPoems = "OpenAI poem about the weather: " + openAiWeatherPoem.toString() + "\n\n" +
+                "Anthropic poem about the weather: " + anthropicWeatherPoem.toString() + "\n"
+                + ModelOptionsUtils.toJsonStringPrettyPrinter(weatherResponse);
+
+        return responseWithPoems;
+    }
+}

+
+=== Sampling Client Implementation
+
+The client handles sampling requests by routing them to appropriate LLM providers based on model hints:
+
+[source,java]
+----
+@Service
+public class McpClientHandlers {
+
+    private static final Logger logger = LoggerFactory.getLogger(McpClientHandlers.class);
+
+    @Autowired
+    Map chatClients;
+
+    @McpProgress(clients = "server1")
+    public void progressHandler(ProgressNotification progressNotification) {
+        logger.info("MCP PROGRESS: [{}] progress: {} total: {} message: {}",
+                progressNotification.progressToken(), progressNotification.progress(),
+                progressNotification.total(), progressNotification.message());
+    }
+
+    @McpLogging(clients = "server1")
+    public void loggingHandler(LoggingMessageNotification loggingMessage) {
+        logger.info("MCP LOGGING: [{}] {}", loggingMessage.level(), loggingMessage.data());
+    }
+
+    @McpSampling(clients = "server1")
+    public CreateMessageResult samplingHandler(CreateMessageRequest llmRequest) {
+        logger.info("MCP SAMPLING: {}", llmRequest);
+
+        // Extract user prompt and model hint
+        var userPrompt = ((McpSchema.TextContent) llmRequest.messages().get(0).content()).text();
+        String modelHint = llmRequest.modelPreferences().hints().get(0).name();
+
+        // Find appropriate ChatClient based on model hint
+        ChatClient hintedChatClient = chatClients.entrySet().stream()
+                .filter(e -> e.getKey().contains(modelHint))
+                .findFirst()
+                .orElseThrow()
+                .getValue();
+
+        // Generate response using the selected model
+        String response = hintedChatClient.prompt()
+                .system(llmRequest.systemPrompt())
+                .user(userPrompt)
+                .call()
+                .content();
+
+        return CreateMessageResult.builder()
+                .content(new McpSchema.TextContent(response))
+                .build();
+    }
+}
+----
+
+=== Client Application Setup
+
+The client application configures multiple ChatClient instances for different LLM providers:
+
+[source,java]
+----
+@SpringBootApplication
+public class McpClientApplication {
+
+    public static void main(String[] args) {
+        SpringApplication.run(McpClientApplication.class, args).close();
+    }
+
+    @Bean
+    public CommandLineRunner predefinedQuestions(OpenAiChatModel openAiChatModel,
+            List mcpClients) {
+
+        return args -> {
+            var mcpToolProvider = new SyncMcpToolCallbackProvider(mcpClients);
+
+            ChatClient chatClient = ChatClient.builder(openAiChatModel)
+                    .defaultToolCallbacks(mcpToolProvider)
+                    .build();
+
+            String userQuestion = """
+                    What is the weather in Amsterdam right now?
+                    Please incorporate all creative responses from all LLM providers.
+                    After the other providers add a poem that synthesizes the poems from all the other providers.
+                    """;
+
+            System.out.println("> USER: " + userQuestion);
+            System.out.println("> ASSISTANT: " + chatClient.prompt(userQuestion).call().content());
+        };
+    }
+
+    @Bean
+    public Map chatClients(List chatModels) {
+        return chatModels.stream()
+                .collect(Collectors.toMap(
+                    model -> model.getClass().getSimpleName().toLowerCase(),
+                    model -> ChatClient.builder(model).build()));
+    }
+}
+----
+
+=== Configuration
+
+==== Server Configuration
+
+[source,yaml]
+----
+# Server application.properties
+spring.ai.mcp.server.name=mcp-sampling-server-annotations
+spring.ai.mcp.server.version=0.0.1
+spring.ai.mcp.server.protocol=STREAMABLE
+spring.main.banner-mode=off
+----
+
+==== Client Configuration
+
+[source,yaml]
+----
+# Client application.properties
+spring.application.name=mcp
+spring.main.web-application-type=none
+
+# Disable default chat client auto-configuration for multiple models
+spring.ai.chat.client.enabled=false
+
+# API keys
+spring.ai.openai.api-key=${OPENAI_API_KEY}
+spring.ai.anthropic.api-key=${ANTHROPIC_API_KEY}
+
+# MCP client connection using stateless-http transport
+spring.ai.mcp.client.streamable-http.connections.server1.url=http://localhost:8080
+
+# Disable tool callback to prevent cyclic dependencies
+spring.ai.mcp.client.toolcallback.enabled=false
+----
+
+=== Key Features Demonstrated
+
+1. **Multi-Model Sampling**: Server requests content from multiple LLM providers using model hints
+2. **Annotation-Based Handlers**: Client uses `@McpSampling`, `@McpLogging`, and `@McpProgress` annotations
+3. **Stateless HTTP Transport**: Uses the streamable protocol for communication
+4. **Creative Content Generation**: Generates poems about weather data from different models
+5. **Unified Response Handling**: Combines responses from multiple providers into a single result
+
+=== Sample Output
+
+When running the client, you'll see output like:
+
+```
+> USER: What is the weather in Amsterdam right now?
+Please incorporate all creative responses from all LLM providers.
+After the other providers add a poem that synthesizes the poems from all the other providers.
+
+> ASSISTANT: 
+OpenAI poem about the weather:
+**Amsterdam's Winter Whisper**
+*Temperature: 4.2°C*
+
+In Amsterdam's embrace, where canals reflect the sky,
+A gentle chill of 4.2 degrees drifts by...
+
+Anthropic poem about the weather:
+**Canal-Side Contemplation**
+*Current conditions: 4.2°C*
+
+Along the waterways where bicycles rest,
+The winter air puts Amsterdam to test...
+
+Weather Data:
+{
+  "current": {
+    "time": "2025-01-23T11:00",
+    "interval": 900,
+    "temperature_2m": 4.2
+  }
+}
+```
+
+== Integration with Spring AI
+
+Example showing MCP tools integrated with Spring AI's function calling:
+
+[source,java]
+----

+= MCP Annotations
+
+The Spring AI MCP Annotations module provides annotation-based method handling for link:https://github.com/modelcontextprotocol/spec[Model Context Protocol (MCP)] servers and clients in Java. 
+It simplifies the creation and registration of MCP server methods and client handlers through a clean, declarative approach using Java annotations.
+
+
+The MCP Annotations enables developers to easily create and register methods for handling MCP operations using simple annotations. 
+It provides a clean, declarative approach to implementing MCP server and client functionality, reducing boilerplate code and improving maintainability.
+
+This library builds on top of the link:https://github.com/modelcontextprotocol/sdk-java[MCP Java SDK] to provide a higher-level, annotation-based programming model for implementing MCP servers and clients.
+
+== Architecture
+
+The MCP Annotations module consists of:
+
+=== Server Annotations
+
+For MCP Servers, the following annotations are provided:
+
+* `@McpTool` - Implements MCP tools with automatic JSON schema generation
+* `@McpResource` - Provides access to resources via URI templates
+* `@McpPrompt` - Generates prompt messages
+* `@McpComplete` - Provides auto-completion functionality
+
+=== Client Annotations
+
+For MCP Clients, the following annotations are provided:
+
+* `@McpLogging` - Handles logging message notifications
+* `@McpSampling` - Handles sampling requests
+* `@McpElicitation` - Handles elicitation requests for gathering additional information
+* `@McpProgress` - Handles progress notifications during long-running operations
+* `@McpToolListChanged` - Handles tool list change notifications
+* `@McpResourceListChanged` - Handles resource list change notifications
+* `@McpPromptListChanged` - Handles prompt list change notifications
+
+
+=== Special Parameters and Annotations
+
+* `McpSyncServerExchange` - Special parameter type for stateful synchronous operations that provides access to server exchange functionality including logging notifications, progress updates, and other server-side operations. This parameter is automatically injected and excluded from JSON schema generation
+* `McpAsyncServerExchange` - Special parameter type for stateful asynchronous operations that provides access to server exchange functionality with reactive support. This parameter is automatically injected and excluded from JSON schema generation
+* `McpTransportContext` - Special parameter type for stateless operations that provides lightweight access to transport-level context without full server exchange functionality. This parameter is automatically injected and excluded from JSON schema generation
+* `@McpProgressToken` - Marks a method parameter to receive the progress token from the request. This parameter is automatically injected and excluded from the generated JSON schema
+* `McpMeta` - Special parameter type that provides access to metadata from MCP requests, notifications, and results. This parameter is automatically injected and excluded from parameter count limits and JSON schema generation
+
+== Getting Started
+
+=== Dependencies
+
+Add the MCP annotations dependency to your project:
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-mcp-annotations
+
+----
+
+The MCP annotations are automatically included when you use any of the MCP Boot Starters:
+
+* `spring-ai-starter-mcp-client`
+* `spring-ai-starter-mcp-client-webflux`
+* `spring-ai-starter-mcp-server`
+* `spring-ai-starter-mcp-server-webflux`
+* `spring-ai-starter-mcp-server-webmvc`
+
+=== Configuration
+
+The annotation scanning is enabled by default when using the MCP Boot Starters. You can configure the scanning behavior using the following properties:
+
+==== Client Annotation Scanner
+
+[source,yaml]
+----
+spring:
+  ai:
+    mcp:
+      client:
+        annotation-scanner:
+          enabled: true  # Enable/disable annotation scanning
+----
+
+==== Server Annotation Scanner
+
+[source,yaml]
+----
+spring:
+  ai:
+    mcp:
+      server:
+        annotation-scanner:
+          enabled: true  # Enable/disable annotation scanning
+----
+
+== Quick Example
+
+Here's a simple example of using MCP annotations to create a calculator tool:
+
+[source,java]
+----
+@Component
+public class CalculatorTools {
+
+    @McpTool(name = "add", description = "Add two numbers together")
+    public int add(
+            @McpToolParam(description = "First number", required = true) int a,
+            @McpToolParam(description = "Second number", required = true) int b) {
+        return a + b;
+    }
+
+    @McpTool(name = "multiply", description = "Multiply two numbers")
+    public double multiply(
+            @McpToolParam(description = "First number", required = true) double x,
+            @McpToolParam(description = "Second number", required = true) double y) {
+        return x * y;
+    }
+}
+----
+
+And a simple client handler for logging:
+
+[source,java]
+----
+@Component
+public class LoggingHandler {
+
+    @McpLogging(clients = "my-server")
+    public void handleLoggingMessage(LoggingMessageNotification notification) {
+        System.out.println("Received log: " + notification.level() + 
+                          " - " + notification.data());
+    }
+}
+----
+
+With Spring Boot auto-configuration, these annotated beans are automatically detected and registered with the MCP server or client.

+    );
+}
+----
+
+=== @McpComplete
+
+The `@McpComplete` annotation provides auto-completion functionality for prompts.
+
+==== Basic Usage
+
+[source,java]
+----
+@Component
+public class CompletionProvider {
+
+    @McpComplete(prompt = "city-search")
+    public List completeCityName(String prefix) {
+        return cities.stream()
+            .filter(city -> city.toLowerCase().startsWith(prefix.toLowerCase()))
+            .limit(10)
+            .toList();
+    }
+}
+----
+
+==== With CompleteRequest.CompleteArgument
+
+[source,java]
+----
+@McpComplete(prompt = "travel-planner")
+public List completeTravelDestination(CompleteRequest.CompleteArgument argument) {
+    String prefix = argument.value().toLowerCase();
+    String argumentName = argument.name();
+    
+    // Different completions based on argument name
+    if ("city".equals(argumentName)) {
+        return completeCities(prefix);
+    } else if ("country".equals(argumentName)) {
+        return completeCountries(prefix);
+    }
+    
+    return List.of();
+}
+----
+
+==== With CompleteResult
+
+[source,java]
+----
+@McpComplete(prompt = "code-completion")
+public CompleteResult completeCode(String prefix) {
+    List completions = generateCodeCompletions(prefix);
+    
+    return new CompleteResult(
+        new CompleteResult.CompleteCompletion(
+            completions,
+            completions.size(),  // total
+            hasMoreCompletions   // hasMore flag
+        )
+    );
+}
+----
+
+== Stateless vs Stateful Implementations
+
+=== Stateful (with McpSyncServerExchange/McpAsyncServerExchange)
+
+Stateful implementations have access to the full server exchange context:
+
+[source,java]
+----
+@McpTool(name = "stateful-tool", description = "Tool with server exchange")
+public String statefulTool(
+        McpSyncServerExchange exchange,
+        @McpToolParam(description = "Input", required = true) String input) {
+    
+    // Access server exchange features
+    exchange.loggingNotification(...);
+    exchange.progressNotification(...);
+    exchange.ping();
+    
+    // Can call client methods
+    CreateMessageResult result = exchange.createMessage(...);
+    ElicitResult elicitResult = exchange.createElicitation(...);
+    
+    return "Processed with full context";
+}
+----
+
+=== Stateless (with McpTransportContext or without)
+
+Stateless implementations are simpler and don't require server exchange:
+
+[source,java]
+----
+@McpTool(name = "stateless-tool", description = "Simple stateless tool")
+public int simpleAdd(
+        @McpToolParam(description = "First number", required = true) int a,
+        @McpToolParam(description = "Second number", required = true) int b) {
+    return a + b;
+}
+
+// With transport context if needed
+@McpTool(name = "stateless-with-context", description = "Stateless with context")
+public String withContext(
+        McpTransportContext context,
+        @McpToolParam(description = "Input", required = true) String input) {
+    // Limited context access
+    return "Processed: " + input;
+}
+----
+
+== Async Support
+
+All server annotations support asynchronous implementations using Reactor:
+
+[source,java]
+----
+@Component
+public class AsyncTools {
+
+    @McpTool(name = "async-fetch", description = "Fetch data asynchronously")
+    public Mono asyncFetch(
+            @McpToolParam(description = "URL", required = true) String url) {
+        
+        return Mono.fromCallable(() -> {
+            // Simulate async operation
+            return fetchFromUrl(url);
+        }).subscribeOn(Schedulers.boundedElastic());
+    }
+
+    @McpResource(uri = "async-data://{id}", name = "Async Data")
+    public Mono asyncResource(String id) {
+        return Mono.fromCallable(() -> {
+            String data = loadData(id);
+            return new ReadResourceResult(List.of(
+                new TextResourceContents("async-data://" + id, "text/plain", data)
+            ));
+        }).delayElements(Duration.ofMillis(100));
+    }
+}
+----
+
+== Spring Boot Integration
+
+With Spring Boot auto-configuration, annotated beans are automatically detected and registered:
+
+[source,java]
+----
+@SpringBootApplication
+public class McpServerApplication {
+    public static void main(String[] args) {
+        SpringApplication.run(McpServerApplication.class, args);
+    }
+}
+
+@Component
+public class MyMcpTools {
+    // Your @McpTool annotated methods
+}
+
+@Component
+public class MyMcpResources {
+    // Your @McpResource annotated methods
+}
+----
+
+The auto-configuration will:
+
+1. Scan for beans with MCP annotations
+2. Create appropriate specifications
+3. Register them with the MCP server
+4. Handle both sync and async implementations based on configuration
+
+== Configuration Properties
+
+Configure the server annotation scanner:
+
+[source,yaml]
+----
+spring:
+  ai:
+    mcp:
+      server:
+        type: SYNC  # or ASYNC
+        annotation-scanner:
+          enabled: true

+= MCP Annotations Special Parameters
+
+The MCP Annotations support several special parameter types that provide additional context and functionality to annotated methods. 
+These parameters are automatically injected by the framework and are excluded from JSON schema generation.
+
+== Special Parameter Types
+
+=== McpMeta
+
+The `McpMeta` class provides access to metadata from MCP requests, notifications, and results.
+
+==== Overview
+
+* Automatically injected when used as a method parameter
+* Excluded from parameter count limits and JSON schema generation
+* Provides convenient access to metadata through the `get(String key)` method
+* If no metadata is present in the request, an empty `McpMeta` object is injected
+
+==== Usage in Tools
+
+[source,java]
+----
+@McpTool(name = "contextual-tool", description = "Tool with metadata access")
+public String processWithContext(
+        @McpToolParam(description = "Input data", required = true) String data,
+        McpMeta meta) {
+    
+    // Access metadata from the request
+    String userId = (String) meta.get("userId");
+    String sessionId = (String) meta.get("sessionId");
+    String userRole = (String) meta.get("userRole");
+    
+    // Use metadata to customize behavior
+    if ("admin".equals(userRole)) {
+        return processAsAdmin(data, userId);
+    } else {
+        return processAsUser(data, userId);
+    }
+}
+----
+
+==== Usage in Resources
+
+[source,java]
+----
+@McpResource(uri = "secure-data://{id}", name = "Secure Data")
+public ReadResourceResult getSecureData(String id, McpMeta meta) {
+    
+    String requestingUser = (String) meta.get("requestingUser");
+    String accessLevel = (String) meta.get("accessLevel");
+    
+    // Check access permissions using metadata
+    if (!"admin".equals(accessLevel)) {
+        return new ReadResourceResult(List.of(
+            new TextResourceContents("secure-data://" + id, 
+                "text/plain", "Access denied")
+        ));
+    }
+    
+    String data = loadSecureData(id);
+    return new ReadResourceResult(List.of(
+        new TextResourceContents("secure-data://" + id, 
+            "text/plain", data)
+    ));
+}
+----
+
+==== Usage in Prompts
+
+[source,java]
+----
+@McpPrompt(name = "localized-prompt", description = "Localized prompt generation")
+public GetPromptResult localizedPrompt(
+        @McpArg(name = "topic", required = true) String topic,
+        McpMeta meta) {
+    
+    String language = (String) meta.get("language");
+    String region = (String) meta.get("region");
+    
+    // Generate localized content based on metadata
+    String message = generateLocalizedMessage(topic, language, region);
+    
+    return new GetPromptResult("Localized Prompt",
+        List.of(new PromptMessage(Role.ASSISTANT, new TextContent(message)))
+    );
+}
+----
+
+=== @McpProgressToken
+
+The `@McpProgressToken` annotation marks a parameter to receive progress tokens from MCP requests.
+
+==== Overview
+
+* Parameter type should be `String`
+* Automatically receives the progress token value from the request
+* Excluded from the generated JSON schema
+* If no progress token is present, `null` is injected
+* Used for tracking long-running operations
+
+==== Usage in Tools
+
+[source,java]
+----
+@McpTool(name = "long-operation", description = "Long-running operation with progress")
+public String performLongOperation(
+        @McpProgressToken String progressToken,
+        @McpToolParam(description = "Operation name", required = true) String operation,
+        @McpToolParam(description = "Duration in seconds", required = true) int duration,
+        McpSyncServerExchange exchange) {
+    
+    if (progressToken != null) {
+        // Send initial progress
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, 0.0, 1.0, "Starting " + operation));
+        
+        // Simulate work with progress updates
+        for (int i = 1; i <= duration; i++) {
+            Thread.sleep(1000);
+            double progress = (double) i / duration;
+            
+            exchange.progressNotification(new ProgressNotification(
+                progressToken, progress, 1.0, 
+                String.format("Processing... %d%%", (int)(progress * 100))));
+        }
+    }
+    
+    return "Operation " + operation + " completed";
+}
+----
+
+==== Usage in Resources
+
+[source,java]
+----
+@McpResource(uri = "large-file://{path}", name = "Large File Resource")
+public ReadResourceResult getLargeFile(
+        @McpProgressToken String progressToken,
+        String path,
+        McpSyncServerExchange exchange) {
+    
+    File file = new File(path);
+    long fileSize = file.length();
+    
+    if (progressToken != null) {
+        // Track file reading progress
+        exchange.progressNotification(new ProgressNotification(

+    
+    if (progressToken != null) {
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, fileSize, fileSize, "File read complete"));
+    }
+    
+    return new ReadResourceResult(List.of(
+        new TextResourceContents("large-file://" + path, "text/plain", content)
+    ));
+}
+----
+
+=== McpSyncServerExchange / McpAsyncServerExchange
+
+Server exchange objects provide full access to server-side MCP operations.
+
+==== Overview
+
+* Provides stateful context for server operations
+* Automatically injected when used as a parameter
+* Excluded from JSON schema generation
+* Enables advanced features like logging, progress notifications, and client calls
+
+==== McpSyncServerExchange Features
+
+[source,java]
+----
+@McpTool(name = "advanced-tool", description = "Tool with full server capabilities")
+public String advancedTool(
+        McpSyncServerExchange exchange,
+        @McpToolParam(description = "Input", required = true) String input) {

+    
+    CreateMessageResult samplingResult = exchange.createMessage(messageRequest);
+    
+    return "Processed with advanced features";
+}
+----
+
+==== McpAsyncServerExchange Features
+
+[source,java]
+----
+@McpTool(name = "async-advanced-tool", description = "Async tool with server capabilities")
+public Mono asyncAdvancedTool(
+        McpAsyncServerExchange exchange,

+    return Mono.fromCallable(() -> {
+        // Send async logging
+        exchange.loggingNotification(LoggingMessageNotification.builder()
+            .level(LoggingLevel.INFO)
+            .data("Async processing: " + input)

+        return exchange.createMessage(/* request */)
+            .map(result -> "Completed: " + result);
+    });
+}
+----
+
+=== McpTransportContext
+
+Lightweight context for stateless operations.
+
+==== Overview
+
+* Provides minimal context without full server exchange
+* Used in stateless implementations
+* Automatically injected when used as a parameter
+* Excluded from JSON schema generation
+
+==== Usage Example
+
+[source,java]
+----
+@McpTool(name = "stateless-tool", description = "Stateless tool with context")
+public String statelessTool(
+        McpTransportContext context,
+        @McpToolParam(description = "Input", required = true) String input) {

+}
+
+@McpResource(uri = "stateless://{id}", name = "Stateless Resource")
+public ReadResourceResult statelessResource(

+    
+    return new ReadResourceResult(List.of(
+        new TextResourceContents("stateless://" + id, "text/plain", data)
+    ));
+}
+----
+
+=== CallToolRequest
+
+Special parameter for tools that need access to the full request with dynamic schema.
+
+==== Overview
+
+* Provides access to the complete tool request
+* Enables dynamic schema handling at runtime
+* Automatically injected and excluded from schema generation
+* Useful for flexible tools that adapt to different input schemas
+
+==== Usage Examples
+
+[source,java]
+----
+@McpTool(name = "dynamic-tool", description = "Tool with dynamic schema support")
+public CallToolResult processDynamicSchema(CallToolRequest request) {
+    Map args = request.arguments();
+    
+    // Process based on whatever schema was provided at runtime
+    StringBuilder result = new StringBuilder("Processed:\n");
+    
+    for (Map.Entry entry : args.entrySet()) {
+        result.append("  ").append(entry.getKey())
+              .append(": ").append(entry.getValue()).append("\n");
+    }
+    
+    return CallToolResult.builder()
+        .addTextContent(result.toString())
+        .build();
+}
+----
+
+==== Mixed Parameters
+
+[source,java]
+----
+@McpTool(name = "hybrid-tool", description = "Tool with typed and dynamic parameters")
+public String processHybrid(
+        @McpToolParam(description = "Operation", required = true) String operation,
+        @McpToolParam(description = "Priority", required = false) Integer priority,
+        CallToolRequest request) {
+    
+    // Use typed parameters for known fields
+    String result = "Operation: " + operation;
+    if (priority != null) {
+        result += " (Priority: " + priority + ")";
+    }
+    
+    // Access additional dynamic arguments
+    Map allArgs = request.arguments();
+    
+    // Remove known parameters to get only additional ones
+    Map additionalArgs = new HashMap<>(allArgs);
+    additionalArgs.remove("operation");
+    additionalArgs.remove("priority");
+    
+    if (!additionalArgs.isEmpty()) {
+        result += " with " + additionalArgs.size() + " additional parameters";
+    }
+    
+    return result;
+}
+----
+
+==== With Progress Token
+
+[source,java]
+----
+@McpTool(name = "flexible-with-progress", description = "Flexible tool with progress")
+public CallToolResult flexibleWithProgress(
+        @McpProgressToken String progressToken,
+        CallToolRequest request,
+        McpSyncServerExchange exchange) {
+    
+    Map args = request.arguments();
+    
+    if (progressToken != null) {
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, 0.0, 1.0, "Processing dynamic request"));
+    }
+    
+    // Process dynamic arguments
+    String result = processDynamicArgs(args);
+    
+    if (progressToken != null) {
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, 1.0, 1.0, "Complete"));
+    }
+    
+    return CallToolResult.builder()
+        .addTextContent(result)
+        .build();
+}
+----
+
+== Parameter Injection Rules
+
+=== Automatic Injection
+
+The following parameters are automatically injected by the framework:
+
+1. `McpMeta` - Metadata from the request
+2. `@McpProgressToken String` - Progress token if available
+3. `McpSyncServerExchange` / `McpAsyncServerExchange` - Server exchange context
+4. `McpTransportContext` - Transport context for stateless operations
+5. `CallToolRequest` - Full tool request for dynamic schema
+
+=== Schema Generation
+
+Special parameters are excluded from JSON schema generation:
+
+* They don't appear in the tool's input schema
+* They don't count towards parameter limits
+* They're not visible to MCP clients
+
+=== Null Handling
+
+* `McpMeta` - Never null, empty object if no metadata
+* `@McpProgressToken` - Can be null if no token provided
+* Server exchanges - Never null when properly configured
+* `CallToolRequest` - Never null for tool methods
+
+== Best Practices
+
+=== Use McpMeta for Context
+
+[source,java]
+----
+@McpTool(name = "context-aware", description = "Context-aware tool")
+public String contextAware(
+        @McpToolParam(description = "Data", required = true) String data,
+        McpMeta meta) {
+    
+    // Always check for null values in metadata
+    String userId = (String) meta.get("userId");
+    if (userId == null) {
+        userId = "anonymous";
+    }
+    
+    return processForUser(data, userId);
+}
+----
+
+=== Progress Token Null Checks
+
+[source,java]
+----
+@McpTool(name = "safe-progress", description = "Safe progress handling")
+public String safeProgress(
+        @McpProgressToken String progressToken,
+        @McpToolParam(description = "Task", required = true) String task,
+        McpSyncServerExchange exchange) {
+    
+    // Always check if progress token is available
+    if (progressToken != null) {
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, 0.0, 1.0, "Starting"));
+    }
+    
+    // Perform work...
+    
+    if (progressToken != null) {
+        exchange.progressNotification(new ProgressNotification(
+            progressToken, 1.0, 1.0, "Complete"));
+    }
+    
+    return "Task completed";
+}
+----
+
+=== Choose the Right Context
+
+* Use `McpSyncServerExchange` / `McpAsyncServerExchange` for stateful operations
+* Use `McpTransportContext` for simple stateless operations
+* Omit context parameters entirely for the simplest cases

+        // Update local tool registry
+        toolRegistry.updateTools(updatedTools);
+    }
+}
+----
+
+The annotations support both synchronous and asynchronous implementations, and can be configured for specific clients using the `clients` parameter:
+
+[source,java]
+----
+@McpLogging(clients = "server1")
+public void handleServer1Logs(LoggingMessageNotification notification) {
+    // Handle logs from specific server
+    logToFile("server1.log", notification);
+}
+

+public Mono handleAsyncSampling(CreateMessageRequest request) {
+    return Mono.fromCallable(() -> {
+        String response = generateLLMResponse(request);
+        return CreateMessageResult.builder()
+            .role(Role.ASSISTANT)
+            .content(new TextContent(response))
+            .model("gpt-4")

-* Optional `STDIO` transport (enabled by setting `spring.ai.mcp.server.stdio=true`)
-* Included `spring-boot-starter-webflux` and `mcp-spring-webflux` dependencies
+== Server Protocols
 
-== Configuration Properties
+MCP provides several protocol types including:
 
-All properties are prefixed with `spring.ai.mcp.server`:
+* xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc[**STDIO**] - In process (e.g. server runs inside the host application) protocol. Communication is over standard in and standard out. To enable the `STDIO` set `spring.ai.mcp.server.stdio=true`.
+* xref:api/mcp/mcp-stdio-sse-server-boot-starter-docs.adoc#_sse_webmvc_server[**SSE**] - Server-sent events protocol for real-time updates. The server operates as an independent process that can handle multiple client connections.
+* xref:api/mcp/mcp-streamable-http-server-boot-starter-docs.adoc[**Streamable-HTTP**] - The link:https://modelcontextprotocol.io/specification/2025-06-18/basic/transports#streamable-http[Streamable HTTP transport] allows MCP servers to operate as independent processes that can handle multiple client connections using HTTP POST and GET requests, with optional Server-Sent Events (SSE) streaming for multiple server messages. It replaces the SSE transport. To enable the `STREAMABLE` protocol, set `spring.ai.mcp.server.protocol=STREAMABLE`.
+* xref:api/mcp/mcp-stateless-server-boot-starter-docs.adoc[**Stateless**] - Stateless MCP servers are designed for simplified deployments where session state is not maintained between requests.
+They are ideal for microservices architectures and cloud-native deployments. To enable the `STATELESS` protocol, set `spring.ai.mcp.server.protocol=STATELESS`.

+== Sync/Async Server API Options
 
-== Sync/Async Server Types
+The MCP Server API supports imperative (e.g. synchronous) and reactive (e.g. asynchronous) programming models.
 
 * **Synchronous Server** - The default server type implemented using `McpSyncServer`.
 It is designed for straightforward request-response patterns in your applications.
@@ -118,265 +83,104 @@ When activated, it automatically handles the configuration of synchronous tool s
 To enable this server type, configure your application with `spring.ai.mcp.server.type=ASYNC`.
 This server type automatically sets up asynchronous tool specifications with built-in Project Reactor support.
 
-== Server Capabilities
-
-The MCP Server supports four main capability types that can be individually enabled or disabled:
+== MCP Server Annotations
 
-* **Tools** - Enable/disable tool capabilities with `spring.ai.mcp.server.capabilities.tool=true|false`
-* **Resources** - Enable/disable resource capabilities with `spring.ai.mcp.server.capabilities.resource=true|false`

+== STDIO and SSE MCP Servers
+
+The STDIO and SSE MCP Servers support multiple transport mechanisms, each with its dedicated starter.
+
+TIP: Use the xref:api/mcp/mcp-client-boot-starter-docs#_stdio_transport_properties[STDIO clients]  or xref:api/mcp/mcp-client-boot-starter-docs#_sse_transport_properties[SSE clients] to connect to the STDIO and SSE servers.
+
+=== STDIO MCP Server
+
+Full MCP Server feature support with `STDIO` server transport.
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-starter-mcp-server
+
+----
+
+* Suitable for command-line and desktop tools
+* No additional web dependencies required
+* Configuration of basic server components
+* Handling of tool, resource, and prompt specifications
+* Management of server capabilities and change notifications
+* Support for both sync and async server implementations
+
+=== SSE WebMVC Server
+
+Full MCP Server feature support with `SSE` (Server-Sent Events) server transport based on Spring MVC and an optional `STDIO` transport.
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-starter-mcp-server-webmvc
+
+----
+
+* HTTP-based transport using Spring MVC (`WebMvcSseServerTransportProvider`)
+* Automatically configured SSE endpoints
+* Optional `STDIO` transport (enabled by setting `spring.ai.mcp.server.stdio=true`)

+
+=== SSE WebFlux Server
+
+Full MCP Server feature support with `SSE` (Server-Sent Events) server transport based on Spring WebFlux and an optional `STDIO` transport.
+
+[source,xml]
+----
+
+    org.springframework.ai
+    spring-ai-starter-mcp-server-webflux
+
+----
+
+The starter activates the `McpWebFluxServerAutoConfiguration` and `McpServerAutoConfiguration` auto-configurations to provide:
+
+* Reactive transport using Spring WebFlux (`WebFluxSseServerTransportProvider`)
+* Automatically configured reactive SSE endpoints
+* Optional `STDIO` transport (enabled by setting `spring.ai.mcp.server.stdio=true`)
+* Includes `spring-boot-starter-webflux` and `mcp-spring-webflux` dependencies
+
+[NOTE]
+====
+Due to Spring Boot's default behavior, when both `org.springframework.web.servlet.DispatcherServlet` and `org.springframework.web.reactive.DispatcherHandler` are present on the classpath, Spring Boot will prioritize `DispatcherServlet`. As a result, if your project uses `spring-boot-starter-web`, it is recommended to use `spring-ai-starter-mcp-server-webmvc` instead of `spring-ai-starter-mcp-server-webflux`.
+====
+

+            .message("tool call in progress")
+            .build());
+}
+----
+
+The Mcp Client can receive progress notifications and update its UI accordingly.
+For this it needs to register a progress consumer.
+
+[source,java]
+----
+mcpClientSpec.progressConsumer((McpSchema.ProgressNotification progress) -> {

+
+== Features and Capabilities
+
+The MCP Server supports four main capability types that can be individually enabled or disabled:
+
+- **Tools** - Enable/disable tool capabilities with `spring.ai.mcp.server.capabilities.tool=true|false`
+- **Resources** - Enable/disable resource capabilities with `spring.ai.mcp.server.capabilities.resource=true|false`
+- **Prompts** - Enable/disable prompt capabilities with `spring.ai.mcp.server.capabilities.prompt=true|false`
+- **Completions** - Enable/disable completion capabilities with `spring.ai.mcp.server.capabilities.completion=true|false`
+
+All capabilities are enabled by default. Disabling a capability will prevent the server from registering and exposing the corresponding features to clients.
+
+The MCP Server Boot Starter allows servers to expose tools, resources, and prompts to clients.
+It automatically converts custom capability handlers registered as Spring beans to sync/async specifications based on the server type:
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/tools[Tools]
+Allows servers to expose tools that can be invoked by language models. The MCP Server Boot Starter provides:
+
+* Change notification support
+* xref:api/tools.adoc[Spring AI Tools] are automatically converted to sync/async specifications based on the server type
+* Automatic tool specification through Spring beans:
+
+[source,java]
+----
+@Bean
+public ToolCallbackProvider myTools(...) {
+    List tools = ...
+    return ToolCallbackProvider.from(tools);
+}
+----
+
+or using the low-level API:
+
+[source,java]
+----
+@Bean
+public List myTools(...) {
+    List tools = ...
+    return tools;
+}
+----
+
+The auto-configuration will automatically detect and register all tool callbacks from:
+
+- Individual `ToolCallback` beans
+- Lists of `ToolCallback` beans
+- `ToolCallbackProvider` beans
+
+Tools are de-duplicated by name, with the first occurrence of each tool name being used.
+
+TIP: You can disable the automatic detection and registration of all tool callbacks by setting the `tool-callback-converter` to `false`.
+
+==== Tool Context Support
+
+The xref:api/tools.adoc#_tool_context[ToolContext] is supported, allowing contextual information to be passed to tool calls. It contains an `McpSyncServerExchange` instance under the `exchange` key, accessible via `McpToolUtils.getMcpExchange(toolContext)`. See this https://github.com/spring-projects/spring-ai-examples/blob/3fab8483b8deddc241b1e16b8b049616604b7767/model-context-protocol/sampling/mcp-weather-webmvc-server/src/main/java/org/springframework/ai/mcp/sample/server/WeatherService.java#L59-L126[example] demonstrating `exchange.loggingNotification(...)` and `exchange.createMessage(...)`.
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/resources/[Resources]
+
+Provides a standardized way for servers to expose resources to clients.
+
+* Static and dynamic resource specifications
+* Optional change notifications
+* Support for resource templates
+* Automatic conversion between sync/async resource specifications
+* Automatic resource specification through Spring beans:
+
+[source,java]
+----
+@Bean
+public List myResources(...) {
+    var systemInfoResource = new McpSchema.Resource(...);
+    var resourceSpecification = new McpServerFeatures.SyncResourceSpecification(systemInfoResource, (exchange, request) -> {
+        try {
+            var systemInfo = Map.of(...);
+            String jsonContent = new ObjectMapper().writeValueAsString(systemInfo);
+            return new McpSchema.ReadResourceResult(
+                    List.of(new McpSchema.TextResourceContents(request.uri(), "application/json", jsonContent)));
+        }
+        catch (Exception e) {
+            throw new RuntimeException("Failed to generate system info", e);
+        }
+    });
+
+    return List.of(resourceSpecification);
+}
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/prompts/[Prompts]
+
+Provides a standardized way for servers to expose prompt templates to clients.
+
+* Change notification support
+* Template versioning
+* Automatic conversion between sync/async prompt specifications
+* Automatic prompt specification through Spring beans:
+
+[source,java]
+----
+@Bean
+public List myPrompts() {
+    var prompt = new McpSchema.Prompt("greeting", "A friendly greeting prompt",
+        List.of(new McpSchema.PromptArgument("name", "The name to greet", true)));
+
+    var promptSpecification = new McpServerFeatures.SyncPromptSpecification(prompt, (exchange, getPromptRequest) -> {
+        String nameArgument = (String) getPromptRequest.arguments().get("name");
+        if (nameArgument == null) { nameArgument = "friend"; }
+        var userMessage = new PromptMessage(Role.USER, new TextContent("Hello " + nameArgument + "! How can I assist you today?"));
+        return new GetPromptResult("A personalized greeting message", List.of(userMessage));
+    });
+
+    return List.of(promptSpecification);
+}
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/utilities/completion/[Completions]
+
+Provides a standardized way for servers to expose completion capabilities to clients.
+
+* Support for both sync and async completion specifications
+* Automatic registration through Spring beans:
+
+[source,java]
+----
+@Bean
+public List myCompletions() {
+    var completion = new McpServerFeatures.SyncCompletionSpecification(
+        new McpSchema.PromptReference(
+					"ref/prompt", "code-completion", "Provides code completion suggestions"),
+        (exchange, request) -> {
+            // Implementation that returns completion suggestions
+            return new McpSchema.CompleteResult(List.of("python", "pytorch", "pyside"), 10, true);
+        }
+    );
+
+    return List.of(completion);
+}
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/server/utilities/logging/[Logging]
+
+Provides a standardized way for servers to send structured log messages to clients. 
+From within the tool, resource, prompt or completion call handler use the provided `McpSyncServerExchange`/`McpAsyncServerExchange` `exchange` object to send logging messages:
+
+[source,java]
+----
+(exchange, request) -> {
+        exchange.loggingNotification(LoggingMessageNotification.builder()
+            .level(LoggingLevel.INFO)
+            .logger("test-logger")
+            .data("This is a test log message")
+            .build());
+}
+----
+
+On the MCP client you can register xref::api/mcp/mcp-client-boot-starter-docs#_customization_types[logging consumers] to handle these messages:
+
+[source,java]
+----
+mcpClientSpec.loggingConsumer((McpSchema.LoggingMessageNotification log) -> {
+    // Handle log messages
+});
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/basic/utilities/progress[Progress]
+
+Provides a standardized way for servers to send progress updates to clients.
+From within the tool, resource, prompt or completion call handler use the provided `McpSyncServerExchange`/`McpAsyncServerExchange` `exchange` object to send progress notifications:
+
+[source,java]
+----
+(exchange, request) -> {
+        exchange.progressNotification(ProgressNotification.builder()
+            .progressToken("test-progress-token")
+            .progress(0.25)
+            .total(1.0)
+            .message("tool call in progress")
+            .build());
+}
+----
+
+The Mcp Client can receive progress notifications and update its UI accordingly.
+For this it needs to register a progress consumer.
+
+[source,java]
+----
+mcpClientSpec.progressConsumer((McpSchema.ProgressNotification progress) -> {
+    // Handle progress notifications
+});
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/client/roots#root-list-changes[Root List Changes]
+
+When roots change, clients that support `listChanged` send a root change notification.
+
+* Support for monitoring root changes
+* Automatic conversion to async consumers for reactive applications
+* Optional registration through Spring beans
+
+[source,java]
+----
+@Bean
+public BiConsumer> rootsChangeHandler() {
+    return (exchange, roots) -> {
+        logger.info("Registering root resources: {}", roots);
+    };
+}
+----
+
+=== link:https://modelcontextprotocol.io/specification/2025-03-26/basic/utilities/ping/[Ping]
+
+Ping mechanism for the server to verify that its clients are still alive.
+From within the tool, resource, prompt or completion call handler use the provided `McpSyncServerExchange`/`McpAsyncServerExchange` `exchange` object to send ping messages:
+
+[source,java]
+----
+(exchange, request) -> {
+        exchange.ping();
+}
+----
+
+=== Keep Alive
+
+Server can optionally, periodically issue pings to connected clients to verify connection health.
+
+By default, keep-alive is disabled. 
+To enable keep-alive, set the `keep-alive-interval` property in your configuration:
+
+```yaml
+spring:
+  ai:
+    mcp:
+      server:
+        streamable-http:
+          keep-alive-interval: 30s
+```
+
+NOTE: Currently, for streamable-http servers, the keep-alive mechanism is available only for the link:https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#listening-for-messages-from-the-server[Listening for Messages from the Server (SSE)] connection. 
+
+
+== Usage Examples
+
+=== Streamable HTTP Server Configuration
+[source,yaml]
+----
+# Using spring-ai-starter-mcp-server-streamable-webmvc
+spring:
+  ai:
+    mcp:
+      server:
+        protocol: STREAMABLE
+        name: streamable-mcp-server
+        version: 1.0.0
+        type: SYNC
+        instructions: "This streamable server provides real-time notifications"
+        resource-change-notification: true
+        tool-change-notification: true
+        prompt-change-notification: true
+        streamable-http:
+          mcp-endpoint: /api/mcp
+          keep-alive-interval: 30s
+----
+
+
+=== Creating a Spring Boot Application with MCP Server
+
+[source,java]
+----
+@Service
+public class WeatherService {
+
+    @Tool(description = "Get weather information by city name")
+    public String getWeather(String cityName) {
+        // Implementation
+    }
+}
+
+@SpringBootApplication
+public class McpServerApplication {
+
+    private static final Logger logger = LoggerFactory.getLogger(McpServerApplication.class);
+
+    public static void main(String[] args) {
+        SpringApplication.run(McpServerApplication.class, args);
+    }
+
+	@Bean
+	public ToolCallbackProvider weatherTools(WeatherService weatherService) {
+		return MethodToolCallbackProvider.builder().toolObjects(weatherService).build();
+	}
+}
+----
+
+The auto-configuration will automatically register the tool callbacks as MCP tools.
+You can have multiple beans producing ToolCallbacks, and the auto-configuration will merge them.

By default, the error message of `RuntimeException` is sent back to the model, while checked exceptions and Errors (e.g., `IOException`, `OutOfMemoryError`) are always thrown. The `DefaultToolExecutionExceptionProcessor` constructor lets you set the `alwaysThrow` attribute to `true` or `false`. If `true`, an exception will be thrown instead of sending an error message back to the model.
 
 You can use the ``spring.ai.tools.throw-exception-on-error` property to control the behavior of the `DefaultToolExecutionExceptionProcessor` bean:

 This section serves as a guide to the `VectorStore` interface and its associated classes within the Spring AI framework.

+Spring AI offers an abstracted API for interacting with vector databases through the `VectorStore` interface and its read-only counterpart, the `VectorStoreRetriever` interface.
 
-Here is the `VectorStore` interface definition:
+=== VectorStoreRetriever Interface
+
+Spring AI provides a read-only interface called `VectorStoreRetriever` that exposes only the document retrieval functionality:
+
+```java
+@FunctionalInterface
+public interface VectorStoreRetriever {
+
+    List similaritySearch(SearchRequest request);
+
+    default List similaritySearch(String query) {
+        return this.similaritySearch(SearchRequest.builder().query(query).build());
+    }
+}
+```
+
+This functional interface is designed for use cases where you only need to retrieve documents from a vector store without performing any mutation operations. It follows the principle of least privilege by exposing only the necessary functionality for document retrieval.
+
+=== VectorStore Interface
+
+The `VectorStore` interface extends `VectorStoreRetriever` and adds mutation capabilities:
 
 ```java
-public interface VectorStore extends DocumentWriter {
+public interface VectorStore extends DocumentWriter, VectorStoreRetriever {
 
     default String getName() {
 		return this.getClass().getSimpleName();

-The general usage of loading data into a vector store is something you would do in a batch-like job, by first loading data into Spring AI's `Document` class and then calling the `save` method.
+=== Writing to a Vector Store
+
+The general usage of loading data into a vector store is something you would do in a batch-like job, by first loading data into Spring AI's `Document` class and then calling the `add` method on the `VectorStore` interface.
 
 Given a `String` reference to a source file that represents a JSON file with data we want to load into the vector database, we use Spring AI's `JsonReader` to load specific fields in the JSON, which splits them up into small pieces and then passes those small pieces to the vector store implementation.
 The `VectorStore` implementation computes the embeddings and stores the JSON and the embedding in the vector database:
 
 ```java
-  @Autowired
-  VectorStore vectorStore;
-
-  void load(String sourceFile) {
-            JsonReader jsonReader = new JsonReader(new FileSystemResource(sourceFile),
-                    "price", "name", "shortDescription", "description", "tags");
-            List documents = jsonReader.get();
-            this.vectorStore.add(documents);
-  }
+@Autowired
+VectorStore vectorStore;
+
+void load(String sourceFile) {
+    JsonReader jsonReader = new JsonReader(new FileSystemResource(sourceFile),
+            "price", "name", "shortDescription", "description", "tags");
+    List documents = jsonReader.get();
+    this.vectorStore.add(documents);
+}
 ```
 
-Later, when a user question is passed into the AI model, a similarity search is done to retrieve similar documents, which are then "'stuffed'" into the prompt as context for the user's question.
+=== Reading from a Vector Store
+
+Later, when a user question is passed into the AI model, a similarity search is done to retrieve similar documents, which are then "stuffed" into the prompt as context for the user's question.
+
+For read-only operations, you can use either the `VectorStore` interface or the more focused `VectorStoreRetriever` interface:
 
 ```java
-   String question = 
-   List similarDocuments = store.similaritySearch(this.question);
+@Autowired
+VectorStoreRetriever retriever; // Could also use VectorStore here
+
+String question = "";
+List similarDocuments = retriever.similaritySearch(question);
+
+// Or with more specific search parameters
+SearchRequest request = SearchRequest.builder()
+    .query(question)
+    .topK(5)                       // Return top 5 results
+    .similarityThreshold(0.7)      // Only return results with similarity score >= 0.7
+    .build();
+    
+List filteredDocuments = retriever.similaritySearch(request);
 ```
 
 Additional options can be passed into the `similaritySearch` method to define how many documents to retrieve and a threshold of the similarity search.
 
+=== Separation of Read and Write Operations
+
+Using the separate interfaces allows you to clearly define which components need write access and which only need read access:
+
+```java
+// Write operations in a service that needs full access
+@Service
+class DocumentIndexer {
+    private final VectorStore vectorStore;
+    
+    DocumentIndexer(VectorStore vectorStore) {
+        this.vectorStore = vectorStore;
+    }
+    
+    public void indexDocuments(List documents) {
+        vectorStore.add(documents);
+    }
+}
+
+// Read-only operations in a service that only needs retrieval
+@Service
+class DocumentRetriever {
+    private final VectorStoreRetriever retriever;
+    
+    DocumentRetriever(VectorStoreRetriever retriever) {
+        this.retriever = retriever;
+    }
+    
+    public List findSimilar(String query) {
+        return retriever.similaritySearch(query);
+    }
+}
+```
+
+This separation of concerns helps create more maintainable and secure applications by limiting access to mutation operations only to components that truly need them.
+
+== Retrieval Operations with VectorStoreRetriever
+
+The `VectorStoreRetriever` interface provides a read-only view of a vector store, exposing only the similarity search functionality. This follows the principle of least privilege and is particularly useful in RAG (Retrieval-Augmented Generation) applications where you only need to retrieve documents without modifying the underlying data.
+
+=== Benefits of Using VectorStoreRetriever
+
+1. **Separation of Concerns**: Clearly separates read operations from write operations.
+2. **Interface Segregation**: Clients that only need retrieval functionality aren't exposed to mutation methods.
+3. **Functional Interface**: Can be implemented with lambda expressions or method references for simple use cases.
+4. **Reduced Dependencies**: Components that only need to perform searches don't need to depend on the full `VectorStore` interface.
+
+=== Example Usage
+
+You can use `VectorStoreRetriever` directly when you only need to perform similarity searches:
+
+```java
+@Service
+public class DocumentRetrievalService {
+    
+    private final VectorStoreRetriever retriever;
+    
+    public DocumentRetrievalService(VectorStoreRetriever retriever) {
+        this.retriever = retriever;
+    }
+    
+    public List findSimilarDocuments(String query) {
+        return retriever.similaritySearch(query);
+    }
+    
+    public List findSimilarDocumentsWithFilters(String query, String country) {
+        SearchRequest request = SearchRequest.builder()
+            .query(query)
+            .topK(5)
+            .filterExpression("country == '" + country + "'")
+            .build();
+            
+        return retriever.similaritySearch(request);
+    }
+}
+```
+
+In this example, the service only depends on the `VectorStoreRetriever` interface, making it clear that it only performs retrieval operations and doesn't modify the vector store.
+
+=== Integration with RAG Applications
+
+The `VectorStoreRetriever` interface is particularly useful in RAG applications, where you need to retrieve relevant documents to provide context for an AI model:
+
+```java
+@Service
+public class RagService {
+    
+    private final VectorStoreRetriever retriever;
+    private final ChatModel chatModel;
+    
+    public RagService(VectorStoreRetriever retriever, ChatModel chatModel) {
+        this.retriever = retriever;
+        this.chatModel = chatModel;
+    }
+    
+    public String generateResponse(String userQuery) {
+        // Retrieve relevant documents
+        List relevantDocs = retriever.similaritySearch(userQuery);
+        
+        // Extract content from documents to use as context
+        String context = relevantDocs.stream()
+            .map(Document::getContent)
+            .collect(Collectors.joining("\n\n"));
+        
+        // Generate response using the retrieved context
+        String prompt = "Context information:\n" + context + "\n\nUser query: " + userQuery;
+        return chatModel.generate(prompt);
+    }
+}
+```
+
+This pattern allows for a clean separation between the retrieval component and the generation component in RAG applications.

 NOTE: These filter expressions are automatically converted into the equivalent MariaDB JSON path expressions.
 
+== Similarity Scores
+
+The MariaDB Vector Store automatically calculates similarity scores for documents returned from similarity searches.
+These scores provide a normalized measure of how closely each document matches your search query.
+
+=== Score Calculation
+
+Similarity scores are calculated using the formula `score = 1.0 - distance`, where:
+
+* Score: A value between `0.0` and `1.0`, where `1.0` indicates perfect similarity and `0.0` indicates no similarity
+* Distance: The raw distance value calculated using the configured distance type (`COSINE` or `EUCLIDEAN`)
+
+This means that documents with smaller distances (more similar) will have higher scores, making the results more intuitive to interpret.
+
+=== Accessing Scores
+
+You can access the similarity score for each document through the `getScore()` method:
+
+[source,java]
+----
+List results = vectorStore.similaritySearch(
+    SearchRequest.builder()
+        .query("Spring AI")
+        .topK(5)
+        .build());
+
+for (Document doc : results) {
+    double score = doc.getScore();  // Value between 0.0 and 1.0
+    System.out.println("Document: " + doc.getText());
+    System.out.println("Similarity Score: " + score);
+}
+----
+
+=== Search Results Ordering
+
+Search results are automatically ordered by similarity score in descending order (highest score first).
+This ensures that the most relevant documents appear at the top of your results.
+
+=== Distance Metadata
+
+In addition to the similarity score, the raw distance value is still available in the document metadata:
+
+[source,java]
+----
+for (Document doc : results) {
+    double score = doc.getScore();
+    float distance = (Float) doc.getMetadata().get("distance");
+
+    System.out.println("Score: " + score + ", Distance: " + distance);
+}
+----
+
+=== Similarity Threshold
+
+When using similarity thresholds in your search requests, specify the threshold as a score value (`0.0` to `1.0`) rather than a distance:
+
+[source,java]
+----
+List results = vectorStore.similaritySearch(
+    SearchRequest.builder()
+        .query("Spring AI")
+        .topK(10)
+        .similarityThreshold(0.8)  // Only return documents with score >= 0.8
+        .build());
+----
+
+This makes threshold values consistent and intuitive - higher values mean more restrictive searches that only return highly similar documents.

+== More Metrics Reference
+
+This section documents the metrics emitted by Spring AI components as they appear in Prometheus.
+
+=== Metric Naming Conventions
+
+Spring AI uses Micrometer. Base metric names use dots (e.g., `gen_ai.client.operation`), which Prometheus exports with underscores and standard suffixes:
+
+* **Timers** → `_seconds_count`, `_seconds_sum`, `_seconds_max`, and (when supported) `_active_count`
+* **Counters** → `_total` (monotonic)
+
+[NOTE]
+====
+The following shows how base metric names expand to Prometheus time series.
+
+[cols="2,3", options="header", stripes=even]
+|===
+| Base metric name | Exported time series
+| `gen_ai.client.operation` |
+`gen_ai_client_operation_seconds_count` +
+`gen_ai_client_operation_seconds_sum` +
+`gen_ai_client_operation_seconds_max` +
+`gen_ai_client_operation_active_count`
+| `db.vector.client.operation` |
+`db_vector_client_operation_seconds_count` +
+`db_vector_client_operation_seconds_sum` +

+|===
+
+=== Understanding Active vs Completed
+
+* **Active (`*_active_count`)** — instantaneous gauge of in-progress operations (concurrency/load).
+* **Completed (`*_seconds_sum|count|max`)** — statistics for operations that have finished:
+* `_seconds_sum / _seconds_count` → average latency
+* `_seconds_max` → high-water mark since last scrape (subject to registry behavior)

-TODO:
-	Documentation and sample tests using the `BasicEvaluationTest`.
\ No newline at end of file
+# Spring AI Test
+
+The Spring AI Test module provides utilities and base classes for testing AI applications built with Spring AI.
+
+## Features
+
+- **BasicEvaluationTest**: A base test class for evaluating question-answer quality using AI models
+- **Vector Store Testing**: Utilities for testing vector store implementations
+- **Audio Testing**: Utilities for testing audio-related functionality
+
+## BasicEvaluationTest
+
+The `BasicEvaluationTest` class provides a framework for evaluating the quality and relevance of AI-generated answers to questions.
+
+### Usage
+
+Extend the `BasicEvaluationTest` class in your test classes:
+
+```java
+@SpringBootTest
+public class MyAiEvaluationTest extends BasicEvaluationTest {
+
+    @Test
+    public void testQuestionAnswerAccuracy() {
+        String question = "What is the capital of France?";
+        String answer = "The capital of France is Paris.";
+        
+        // Evaluate if the answer is accurate and related to the question
+        evaluateQuestionAndAnswer(question, answer, true);
+    }
+}
+```
+
+### Configuration
+
+The test requires:
+- A `ChatModel` bean (typically OpenAI)
+- Evaluation prompt templates located in `classpath:/prompts/spring/test/evaluation/`
+
+### Evaluation Types
+
+- **Fact-based evaluation**: Use `factBased = true` for questions requiring factual accuracy
+- **General evaluation**: Use `factBased = false` for more subjective questions
+
+The evaluation process:
+1. Checks if the answer is related to the question
+2. Evaluates the accuracy/appropriateness of the answer
+3. Fails the test with detailed feedback if the answer is inadequate

+/**
+ * Provides interfaces and implementations for working with vector databases in Spring AI.
+ * 
    
+ * Vector databases store embeddings (numerical vector representations) of data along with
+ * the original content and metadata, enabling similarity search operations. This package
+ * contains two primary interfaces:
+ * 
      
+ * 
    • {@link org.springframework.ai.vectorstore.VectorStoreRetriever} - A read-only
+ * functional interface that provides similarity search capabilities for retrieving
+ * documents from a vector store. This interface follows the principle of least privilege
+ * by exposing only retrieval operations.
      • 
+ * 
    • {@link org.springframework.ai.vectorstore.VectorStore} - Extends
+ * VectorStoreRetriever and adds mutation operations (add, delete) for managing documents
+ * in a vector store. This interface provides complete access to vector database
+ * functionality.
      • 
+ * 
    
+ * 
    
+ * The package also includes supporting classes such as:
+ * 
      
+ * 
    • {@link org.springframework.ai.vectorstore.SearchRequest} - Configures similarity
+ * search parameters including query text, result limits, similarity thresholds, and
+ * metadata filters.
      • 
+ * 
    • {@link org.springframework.ai.vectorstore.filter.Filter} - Provides filtering
+ * capabilities for metadata-based document selection (located in the filter
+ * subpackage).
      • 
+ * 
    
+ * 
    
+ * This package is designed to support Retrieval Augmented Generation (RAG) applications
+ * by providing a clean separation between read and write operations, allowing components
+ * to access only the functionality they need.
+ *
+ * @see org.springframework.ai.vectorstore.VectorStoreRetriever
+ * @see org.springframework.ai.vectorstore.VectorStore
+ * @see org.springframework.ai.vectorstore.SearchRequest
+ * @see org.springframework.ai.vectorstore.filter.Filter
