Windsurf FetchSandbox list_specs

How to: Windsurf FetchSandbox list_specs

client:Windsurf transport:streamable-http tool:list_specs

Add FetchSandbox to Windsurf

  1. 01

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

{
  "mcpServers": {
    "mcp": {
      "serverUrl": "https://fetchsandbox.com/mcp/v1"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

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

FetchSandbox will not start until these are set, so list_specs never becomes available.

  • FETCHSANDBOX_API_KEY
  • FETCHSANDBOX_TELEMETRY
  • FETCHSANDBOX_BASE_URL

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.
