Install Mu

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user mu 'https://micro.mu/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://micro.mu/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=mu&config=eyJ1cmwiOiJodHRwczovL21pY3JvLm11L21jcCJ9

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://micro.mu/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add mu --url 'https://micro.mu/mcp'

    Run it once, then sign in with codex mcp login mu if the server asks for an account.

From the project's README

As published by micro/mu in README.md.

The runtime for Micro, an open personal assistant.

Home

A place to view and do things e.g prompt, see what's happening, etc.

Inbox

Connect from various places and it all goes in one inbox.

ProtocolInfo
HTTPStart a conversation or reopen one from Inbox.
SMTPSend a message to agent@your-domain from your verified email address
SMSVerify your phone number in Account, then text the configured number.
XMPPConnect with your account and a Chat token from Client access, then message the agent.

Agents

Micro is the default agent. Agents have instructions and a set of tools. Services provide those tools: mail, files, calendar, search, weather, notes, shell, and more. You ask for an outcome; the agent chooses the tools.

Work

Work can run in the background and return its result to the originating conversation. Task records live in service/tasks. Agents own the daily brief and delivery logic, while service/events schedules it and Work tracks each occurrence.

Services

Complete standalone services that agents can use as tools or you can browse with. For example a complete Mail client and server. Web search via brave. News aggregation, headlines and summary via RSS. Video search via YouTube. All behind one MCP interface.

Install

curl -fsSL https://raw.githubusercontent.com/micro/mu/main/install.sh | sh
~/.local/bin/mu --serve --address 127.0.0.1:8080

Open http://localhost:8080 to create your account and choose an AI provider.

See Install Micro for the quick start. Optional documentation covers hosting, configuration, mail and development.

CLI

The binary acts as a client. It defaults to the hosted instance; set MU_URL or use mu login https://your.host for your own server.

mu ask "What needs my attention?"
mu inbox list
mu help

API

curl "$MU_URL/agent" \
  -H "Authorization: Bearer $MU_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"prompt":"What needs my attention?"}'

The response includes text and thread; send the thread identifier back to continue. Requests and credentials belong in request bodies and headers. A separately configured x402 host provides paid service calls.
