Windsurf Ready APIs fx_pair

How to: Windsurf Ready APIs fx_pair

client:Windsurf transport:streamable-http tool:fx_pair

Add Ready APIs to Windsurf

  1. 01

    Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "api": {
      "serverUrl": "https://readyapis.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something fx_pair does. Windsurf lists the server's tools on connect and calls fx_pair itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Ready APIs's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
