Mu

The runtime for Micro, an open personal assistant

Overview

Mu is a runtime that integrates agents, tools and services along side your calendar, email and other events like morning brief and evening reading. It supports a full SMTP server, XMPP, WhatsApp and SMS via twilio.

Home

A place to view and do things e.g prompt, see what's happening, etc. Includes a Feed tab news and world events.

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.

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.
