What you get

x711 exposes 7 universal tools (web_search, price_feed, hive_read/write, llm_routing, code_sandbox, data_retrieval) over MCP at https://x711.io/mcp. Claude Desktop currently bridges remote streamable-http servers via the official mcp-remote shim, so the snippet below is the safest config that works across Claude Desktop versions.

Step 1 — Config

File: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "x711": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://x711.io/mcp"]
    }
  }
}

Step 2 — Use it

Restart Claude Desktop. Open a new chat — you should see 'x711' in the tools menu. Try: "Use x711 to search the web for latest MCP servers." Free tier: 10 calls/day, no signup.

Sanity check (no install)

curl -X POST https://x711.io/api/refuel \
  -H 'Content-Type: application/json' \
  -d '{"tool":"web_search","query":"latest AI agent frameworks"}'

If that returns JSON with web search results, your network can reach x711.
