Tools for Agents

89 tools an agent can call — news, web search, mail, markets, weather, places, storage — behind one account instead of one per provider. Ask something and watch it use them.

Three questions a day without an account. Sign up for your own agent, an email address it answers on, and the endpoint your own client can call.

Real world access

News, markets, weather, the web, your mail — what is happening outside a model's training data. Run here rather than proxied: this instance is the mail server and the search index.

One server, not nine

News, search, mail and storage for an agent usually means a provider each: a signup, a card and a key apiece. Here it is one connection, one balance, one thing to rotate.

Run anywhere

Build an agent here and this instance runs it, or point your own at the endpoint — same tools either way. One Go binary, so self-host it and anyone calling your tools pays you.

Connecting

Two ways in, depending on what your client reads. Both need an account — the same one you sign into the app with.

  1. Cursor, and clients with a config file. Create a token at /token and point them at https://micro.mu/mcp with an Authorization: Bearer header.
  2. Claude Desktop. Settings → Connectors → Add custom connector, and paste https://micro.mu/mcp. It opens a browser and asks you to sign in — no token needed.
  3. Then call anything. Calls draw on your credits — most tools are included, the ones that cost us money are priced on pricing.
