Add x711 to Claude Desktop

Anthropic's official desktop app — the original MCP host.

Manual config

Paste this into macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "x711": {
      "url": "https://x711.io/mcp",
      "transport": "http",

    }
  }
}

Verify it's live

1. Restart Claude Desktop.
2. In a new chat, ask the assistant: "Use x711 to look up the current ETH price".
3. You should see a tool-call to price_feed with a real result + a transaction_id.

Free tier — no signup. Set X-API-Key in headers later for paid tools and credits.
