You can connect ACP agents with MCP clients through a dedicated bridge that handles multiple transports, automatic agent discovery, smart routing, and interactive sessions. This MCP server enables seamless integration between ACP-based AI agents and MCP-compatible tools, letting you run and coordinate agents from your MCP client with minimal setup.

How to use

You run the MCP server locally and connect your MCP client to it. Start with the default STDIO transport for Claude Desktop compatibility, or choose streaming transports like SSE or a REST-style HTTP flow when you need web integration. The server automatically discovers ACP agents you have running and routes requests to the best matching agent. Use interactive sessions for multi-turn conversations and take advantage of multi-modal support to handle different content types.

How to install

Prerequisites you need before installing are Python 3.11 or newer and a running ACP server with agents. You will also use FastMCP for the MCP protocol implementation.

# Install from PyPI
pip install acp-mcp-server

# Or run in an isolated environment using uvx
uvx acp-mcp-server

Additional notes

Environment variables that affect how the MCP server connects to ACP are as follows. You can set ACP_BASE_URL to point to your ACP server. The default is http://localhost:8000.

# Example environment variable
export ACP_BASE_URL=http://localhost:8000

Configuration and commands

The primary way to run the server is a simple STDIO command, which is suitable for local development and Claude Desktop workflows. If you prefer streaming or REST-like transport, you can pass transport options and ports as shown in the usage examples.
