How it works

The home screen shows cards — a summary of each service. Each card links to a full page. News card shows headlines, links to /news. Markets card shows prices, links to /markets. Everything at a glance, details one tap away.

For developers

Mu exposes a REST API and MCP server at /mcp so AI agents and tools can connect directly.

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

30+ tools — news, search, weather, places, video, email, markets — accessible via MCP. AI agents can pay per-request with USDC through the x402 protocol. No API keys. No accounts. Just call and pay.

See API docs · MCP docs

CLI

Every MCP tool is also available as a mu subcommand. The same binary runs the server (mu --serve) and the CLI — with no arguments it becomes a thin client that talks to /mcp.

mu news                                 # latest news feed
mu news_search "ai safety"              # search news
mu chat "hello"                         # chat with the AI
mu agent "what is the btc price?"       # run the full agent
mu web_search "claude code"             # search the web
mu weather_forecast --lat 51.5 --lon -0.12
mu blog_create --title "Hi" --content "..."
mu apps_build --prompt "a pomodoro timer"
mu me                                   # your account
mu help                                 # full tool list
mu help apps_build                      # parameters for a specific tool

The CLI is registry-driven — every tool added to the MCP server automatically becomes a CLI command. Flags map to tool parameters.

Authentication

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

Config

Loaded from $XDG_CONFIG_HOME/mu/config.json (default ~/.config/mu/config.json). Override with MU_URL / MU_TOKEN or --url / --token flags.

Output

Pretty-printed JSON when attached to a terminal, raw JSON when piped — so mu news | jq '.feed[0]' works. Use --table to render list results as a text table.

See CLI docs for more.

Pricing

Browsing is included. AI and search features use credits — 1 credit = 1p, pay as you go.

• Card — Top up via Stripe. 1 credit = 1p.
• Crypto — AI agents pay per-request with USDC via x402. No account needed.

See Wallet & Credits for details.
