Mu MCP Server

The runtime for Micro, a personal assistant. Ask on the web, send an email, or message it from your phone. Mu runs the assistant, its tools, and your saved conversations in one Go binary that you can host yourself. Try the hosted instance at micro.mu.

Teams that work with micro and want a hosted endpoint instead of running a local process. The project is written in Go.
