+# MCP Everything Server
+
+A comprehensive example MCP server that demonstrates all features of the Model Context Protocol, including:
+
+- Tools with progress reporting, logging, and elicitation
+- Resource handling (static, dynamic, and templated)
+- Prompts with arguments
+- Completion support for resource templates and prompts
+- Request context propagation
+- Notifications and logging
+- Sampling capabilities
+- Structured output
+
+## Usage
+
+### Running the server
+
+```bash
+uv run mcp-server-everything
+```
+
+### Testing with MCP Inspector
+
+```bash
+mcp dev "uv run mcp-server-everything"
+```
+
+### Installing in Claude Desktop
+
+```bash
+mcp install "uv run mcp-server-everything" --name "Everything Server"
+```
+
+## Features
+
+This server demonstrates:
+
+- **Tools**: Echo, progress tracking, sampling, notifications, context access, elicitation
+- **Resources**: Static resources, dynamic resources with parameters, resource templates
+- **Prompts**: Simple and complex prompts with arguments
+- **Completions**: Context-aware completion for prompts and resource templates
+- **Notifications**: Progress updates, logging at different levels, resource/tool list changes
+- **Elicitation**: Interactive user input during tool execution
