Windsurf TokenZero calculate_model_arbitrage

How to: Windsurf TokenZero calculate_model_arbitrage

client:Windsurf transport:streamable-http tool:calculate_model_arbitrage

Add TokenZero to Windsurf

  1. 01

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

{
  "mcpServers": {
    "mcp": {
      "serverUrl": "https://api.tokenzero.sh/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that TokenZero'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

Set these first

TokenZero will not start until these are set, so calculate_model_arbitrage never becomes available.

  • TOKENZERO_URL
  • TOKENZERO_KEY

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 26 October 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.
