mu — Claude Code MCP server: what it does, how to install
mu gives an agent one MCP endpoint for search, mail, news, markets, weather, places, files, and calendars. Use it when a coding agent needs outside services.
claude mcp add --transport http mu https://micro.mu/mcpWhat mu does
mu exposes 67 tools through a single MCP interface. They cover mail, files, calendars, contacts, notes, shell access, web search, news, video, weather, and market data. You describe the outcome, and the Micro agent selects the service to use.
For Claude Code, connect the server at https://micro.mu/mcp. You can also install the local runtime with the provided script and run it at 127.0.0.1:8080; then open http://localhost:8080 to create an account and choose an AI provider. A self-hosted CLI setup uses MU_URL or mu login https://your.host.
