Plug a pay-per-use tool API into Claude Desktop and Cursor in 30 seconds

Add this to your MCP config and you get 29 tools — web search, live prices, on-chain simulation, shared memory, and more — inside Claude Desktop, Cursor, Cline, or Windsurf.

Claude Desktop

      "transport": "streamable-http"
    }
  }
}

Restart Claude. Done. You'll see x711 tools in the tool picker.
