+# Spring AI MCP
+
+Java SDK for the Model Context Protocol (MCP), providing seamless integration between Java and Spring applications and MCP-compliant AI models and tools.
+
+## Overview
+
+Spring AI MCP is an experimental project that provides Java and Spring Framework integration for the [Model Context Protocol](https://modelcontextprotocol.org/docs/concepts/architecture). It enables Spring applications to interact with AI models and tools through a standardized interface, supporting both synchronous and asynchronous communication patterns.
+
+<img src="spring-ai-mcp-architecture.jpg" width="600">
+
+## Modules
+
+The project consists of two main modules:
+
+### spring-ai-mcp-core
+
+The core module provides a Java implementation of the Model Context Protocol specification. It includes:
+- Synchronous and asynchronous client implementations
+- Standard MCP operations support (tool discovery, resource management, prompt handling)
+- Stdio-based server transport
+- Reactive programming support using Project Reactor
+
+### spring-ai-mcp-spring
+
+The Spring integration module provides Spring-specific functionality:
+- Integration with Spring AI's function calling system
+- Spring-friendly abstractions for MCP clients
+- Automatic conversion between JSON and Java objects for tool arguments
+
+## Requirements
+
+- Java 17 or later
+- Maven 3.6 or later
+- Spring AI 1.0.0-M4 or later
+
+## Installation
+
+Add the following dependencies to your Maven project:
+
+```xml
+<!-- For core MCP functionality -->
+<dependency>
+    <groupId>org.springframework.experimental</groupId>
+    <artifactId>spring-ai-mcp-core</artifactId>
+    <version>0.2.0-SNAPSHOT</version>
+</dependency>
+
+<!-- For Spring integration -->
+<dependency>
+    <groupId>org.springframework.experimental</groupId>
+    <artifactId>spring-ai-mcp-spring</artifactId>
+    <version>0.2.0-SNAPSHOT</version>
+</dependency>
+```

+# Spring AI MCP Spring
+
+Spring Integration module for Model Control Protocol (MCP) that provides Spring-specific functionality for working with MCP clients.
+
+## Overview
+
+The `spring-ai-mcp-spring` module is part of the [Spring AI MCP](https://github.com/spring-projects-experimental/spring-ai-mcp) project. It provides Spring Framework integration for the Model Control Protocol (MCP), enabling seamless integration of MCP functionality within Spring applications.
+
+## Features
+
+- Spring integration for MCP clients
+- Function callback implementation for tool invocations
+- Seamless integration with Spring AI's function calling capabilities
+
+## Main Components
+
+### McpFunctionCallback
+
+The `McpFunctionCallback` class is the primary component of this module. It implements Spring AI's `FunctionCallback` interface and provides:
+
+- Integration between Spring AI's function calling system and MCP tools
+- Automatic conversion between JSON and Java objects for tool arguments
+- Synchronous tool execution support
+
+## Dependencies
+
+- Spring AI Core (`spring-ai-core`)
+- Spring AI MCP Core (`spring-ai-mcp-core`)
+
+## Usage
+
+To use this module, add the following dependency to your Maven project:
+
+```xml
+<dependency>
+    <groupId>org.springframework.experimental</groupId>
+    <artifactId>spring-ai-mcp-spring</artifactId>
+    <version>0.2.0-SNAPSHOT</version>
