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

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