 # mcp-python
-Model Context Protocol implementation for Python
+
+Python implementation of the Model Context Protocol (MCP), providing both client and server capabilities for integrating with LLM surfaces.
+
+## Overview
+
+The Model Context Protocol allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This Python SDK implements the full MCP specification, making it easy to:
+
+- Build MCP clients that can connect to any MCP server
+- Create MCP servers that expose resources, prompts and tools
+- Use standard transports like stdio and SSE
+- Handle all MCP protocol messages and lifecycle events
+
+## Installation
+
+```bash
+uv add mcp-python
+```
+
+## Quick Start
+
+### Creating a Client
+
+```python
+from mcp_python import ClientSession
+from mcp_python.client.stdio import stdio_client
+
+async with stdio_client(command="path/to/server") as (read, write):
+    async with ClientSession(read, write) as session:
+        # Initialize the connection
+        await session.initialize()
+
+        # List available resources
+        resources = await session.list_resources()
+```
+
+### Creating a Server
+
+```python
+from mcp_python.server import Server
+from mcp_python.server.stdio import stdio_server
+
+# Create a server instance
+server = Server("example-server")
+
+# Add capabilities
+@server.list_resources()
+async def list_resources():
+    return [
+        {
+            "uri": "file:///example.txt",
+            "name": "Example Resource"
+        }
+    ]
+
+# Run the server
+async with stdio_server() as (read, write):
+    await server.run(read, write, server.create_initialization_options())
+```
