Mcacp MCP Server

Bridge any MCP client to any ACP coding agent. MCACP is an MCP server that speaks the Agent Client Protocol on behalf of your MCP host. It lets Claude Code, Zed, VS Code, or any MCP-compatible client spawn, manage, and interact with ACP coding agents - turning a single chat window into a multi-agent control plane. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
