Windsurf (Codeium) + x711

Hook x711 into Windsurf's Cascade agent.

What you get

Windsurf's Cascade supports MCP servers via its config file. After adding x711 below, Cascade can autonomously call x711 tools when it needs web search, price data, or persistent memory.

Step 1 — Config

File: ~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "x711": {
      "serverUrl": "https://x711.io/mcp"
    }
  }
}

Step 2 — Use it

Restart Windsurf. Open Cascade and ask it to search the web — it will route through x711 automatically.

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.

Available tools

All prices in USDC, billed per call. Free tier waives the first 10 calls/day.

Why x711 is legit

• Open spec. agent.json · OpenAPI 3.1 · x402 manifest
• Open treasury. Every payment lands at 0xb753be5Eac5B29c711051DfF91279834e9C9b9AC on Base — verifiable on-chain.
• Open ledger. /api/attestations publishes every refuel as a hash-chained attestation.
• Live signal. /api/stats/live is an SSE stream of real refuels.
