ACP-MCP-Server
A bridge server that connects Agent Communication Protocol (ACP) agents with Model Context Protocol (MCP) clients, enabling seamless integration between ACP-based AI agents and MCP-compatible tools like Claude Desktop.
✨ Features
- 🔄 Protocol Bridge: Seamlessly connects ACP agents with MCP clients
- 🚀 Multiple Transports: Supports STDIO, SSE, and Streamable HTTP
- 🤖 Agent Discovery: Automatic discovery and registration of ACP agents
- 🧠 Smart Routing: Intelligent routing of requests to appropriate agents
- 🔄 Async Support: Full support for synchronous and asynchronous operations
- 💬 Interactive Sessions: Support for multi-turn agent interactions
- 🌐 Multi-Modal: Handle text, images, and other content types
🚀 Quick Start
Installation
bash
# Install from PyPI
pip install acp-mcp-server
# Or use uvx for isolated execution
uvx acp-mcp-serverBasic Usage
bash
# Run with STDIO (default, for Claude Desktop)
acp-mcp-server
# Run with SSE transport
acp-mcp-server --transport sse --port 8000
# Run with HTTP transport
acp-mcp-server --transport streamable-http --host 0.0.0.0 --port 9000
# Connect to different ACP server
acp-mcp-server --acp-url http://localhost:8001Using with Claude Desktop
Add to your Claude Desktop configuration:
json
{
"mcpServers": {
"acp-bridge": {
"command": "uvx",
"args": ["acp-mcp-server"]
}
}
}📋 Requirements
- Python 3.11+
- Running ACP server with agents
- FastMCP for protocol implementation

Quick Start with Docker
bash
# Build the image
docker build -t acp-mcp-server .
# Run with Streamable HTTP transport
docker run -p 9000:9000 acp-mcp-server
# Run with SSE transport
docker run -p 8000:8000 acp-mcp-server \
--transport sse --host 0.0.0.0 --port 8000
# Connect to custom ACP server
docker run -p 9000:9000 -e ACP_BASE_URL=http://my-acp-server:8001 acp-mcp-serverUsing Docker Compose
bash
# Run HTTP transport service
docker-compose up acp-mcp-http
# Run SSE transport service
docker-compose up acp-mcp-sse
# Run both services
docker-compose up
# Run development mode with live code reload
docker-compose --profile dev up acp-mcp-devProduction Docker Image
For production deployments, use the multi-stage Dockerfile:
bash
# Build production image
docker build -f Dockerfile.prod -t acp-mcp-server:prod .
# Run production container
docker run -d \
--name acp-mcp-server \
--restart unless-stopped \
-p 9000:9000 \
-e ACP_BASE_URL=http://your-acp-server:8000 \
