mu

Tools for agents

Overview

Mu is an MCP server and web app for agents and humans. It provides access to the real world through MCP for the agents and let's humans browse or interact with same content in a web app. Access news, web search, mail, markets, weather, video, places, images, files, events, contacts and more.

Use it live at micro.mu, or self-host.

Usage

{
  "mcpServers": {
    "mu": {
      "url": "https://micro.mu/mcp"
    }
  }
}

Create a Personal Access Token at /token and send it as Authorization: Bearer.

curl -X POST https://micro.mu/mcp -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Scope the connection to the services you need:

https://micro.mu/mcp?tools=news,web,mail

That's what gets listed to your agent. Everything else is still callable.

Browse the tools: micro.mu/tools — every tool, grouped by service, with what each call costs.

See MCP docs for the protocol details.

Request a tool

Open an issue and say what it should do.

The app

The server includes a web app with a home screen. Cards render each service at a glance (headlines, prices, weather, unread mail) and the agent sits inline to act on what you're looking at. Logged-out visitors get a public version with live data.

An LLM — Claude, Atlas Cloud (DeepSeek), or a local Ollama / OpenAI-compatible endpoint — calls the services as tools, composes answers, and keeps per-user memory across sessions.

Sign in with a username and password, a passkey (WebAuthn), or Google. For the CLI, generate a Personal Access Token at /token.

CLI

Every tool is a mu subcommand. The same binary runs the server (mu --serve) and the CLI.

mu news list                            # latest headlines
mu news search "ai safety"              # search news
mu web search "claude code"             # search the web
mu markets list --category stocks       # live prices
mu agent "what is the btc price?"       # run the full agent
mu weather forecast --lat 51.5 --lon -0.12
mu wallet                               # your balance
mu help                                 # full tool list

Every tool in the table above is a command: the service, then the method. The underscore form works too, so mu news list and mu news_list are the same call.

The CLI is registry-driven — a tool added to the server automatically becomes a CLI command.

mu login                  # opens /token in your browser, paste the PAT back
mu config set token xxx   # or set it directly
export MU_TOKEN=xxx       # or use the environment

See CLI docs.

Discord & Telegram

Talk to the agent from Discord or Telegram — questions, markets, news, all from chat. Join the Discord

Every tool is a command on both, in the same two-word shape as the CLI: /news list, /markets list category:stocks, /prayer times. Discord gets one slash command per service with the methods as subcommands; on Telegram you type /news list. Both also take /agent <question> for anything that needs composing, and /usage for your own stats.

Setup for both is in Installation.

Self-hosting

curl -fsSL https://raw.githubusercontent.com/micro/mu/main/install.sh | sh

# Docker
git clone https://github.com/micro/mu && cd mu
docker compose up

# From source
git clone https://github.com/micro/mu
cd mu && go install
mu --serve

First-run setup

Open http://localhost:8080 and Mu walks you through a one-time setup: create your admin account and pick an AI provider (Claude, Atlas Cloud, or a local Ollama / OpenAI-compatible endpoint). That's enough to have a working agent.

For terminal setup. Configure the provider headless, then start the server:

mu setup        # pick a provider, paste a key
mu --serve      # first account you create becomes admin

Or set everything by hand:

export ADMIN=you@example.com          # who's admin (else: first account)
export ATLAS_API_KEY=xxx              # or ANTHROPIC_API_KEY, or OPENAI_BASE_URL
mu --serve

Once you're admin, every other key (YouTube, Brave search, weather, mail/DKIM, Google sign-in…) is configurable from /admin/env in the browser.

See Installation guide.

Configuration
