Windsurf NZ Data API nz_working_days

How to: Windsurf NZ Data API nz_working_days

client:Windsurf transport:streamable-http tool:nz_working_days

Add NZ Data API to Windsurf

01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "nz-data-api": {
      "serverUrl": "https://nzdata.zakwins.workers.dev/mcp"
    }
  }
}

02
Save the file and restart Windsurf.
03
Ask for something nz_working_days does. Windsurf lists the server's tools on connect and calls nz_working_days itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that NZ Data API'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 18 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.
