Windsurf RateAPI — live US mortgage, auto, HELOC, personal & deposit rates save_cohort

How to: Windsurf RateAPI — live US mortgage, auto, HELOC, personal & deposit rates save_cohort

client:Windsurf transport:streamable-http tool:save_cohort

Add RateAPI — live US mortgage, auto, HELOC, personal & deposit rates to Windsurf

  1. 01

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

{
  "mcpServers": {
    "mcp": {
      "serverUrl": "https://mcp.rateapi.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that RateAPI — live US mortgage, auto, HELOC, personal & deposit rates'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.
