Overview

This project demonstrates how to implement and use Anthropic's Model Context Protocol (MCP) with AWS Bedrock. It provides a client implementation that can interact with MCP-enabled tools through AWS Bedrock's runtime service.

Prerequisites

• Python 3.10 or higher
• AWS account with Bedrock access
• Configured AWS credentials
• UV package manager

Project Structure

• client_stdio.py: Main client implementation for interacting with Bedrock and MCP tools using stdio mode
• client_sse.py: Main client implementation for interacting with Bedrock and MCP tools using sse mode
• mcp_simple_tool/: Directory containing the MCP tool implementation
  • server.py: MCP tool server implementation
  • __main__.py: Entry point for the tool
• pyproject.toml: Project dependencies and configuration

Usage

Run the stdio client with:

uv pip install boto3
uv run client_stdio.py

The client will:

1. Initialize a connection to AWS Bedrock
2. Start the MCP tool server
3. List available tools and convert them to the format required by Bedrock
4. Handle communication between Bedrock and the MCP tools

Run the sse client with:

# server
uv pip install boto3 uvicorn
uv run mcp-simple-tool --transport sse --port 8000

# client
uv run client_sse.py

Features

• Seamless integration with AWS Bedrock runtime
• Tool format conversion for Bedrock compatibility
• Asynchronous communication handling
• Structured logging for debugging
