Show HN: Mu – Tools for Agents
Mu is an open‑source platform that offers agents access to a wide range of real internet services through a single MCP endpoint. It provides 67 built‑in tools such as web search, mail, storage, and a wallet, all implemented as native Go services without external dependencies. The system can be used via a hosted instance or self‑hosted as a single binary, and integrates with agents like Claude Desktop and Cursor through the MCP authorization spec.
- ▪Mu consolidates many everyday internet functions—news, search, mail, markets, weather, and more—into one unified API endpoint.
- ▪The platform runs its own implementations of services like SMTP with DKIM, a feed aggregator, and a storage backend, avoiding reliance on third‑party wrappers.
- ▪Mu is released under the AGPL‑3.0 license and can be accessed either through the hosted micro.mu service or by self‑hosting the provided Go binary.

Opening excerpt (first ~120 words) tap to expand
mu Tools for agents Overview Mu gives an agent the everyday internet as tools: news, web search, mail, markets, weather, video, places, images, files, calendar, contacts. 67 of them, behind one MCP endpoint. Connect once and your agent has all of them, instead of wiring up a server for each. Real tools, not wrappers. Most things offering an agent tools are a thin layer over somebody else's API. Mu runs the mail server (SMTP with DKIM), the feed aggregator, the search index, the app sandbox and the wallet it hands you. mail_inbox reads a real inbox. db_create writes to real storage. The tools aren't a catalogue of other people's products — they're this instance's own capabilities, exposed. There is also a web app on the same tools, because the operator is a person too.
