Windsurf Web & domain tools validators__uk-postcode

How to: Windsurf Web & domain tools validators__uk-postcode

client:Windsurf transport:streamable-http tool:validators__uk-postcode

Add Web & domain tools to Windsurf

  1. 01

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

{
  "mcpServers": {
    "web": {
      "serverUrl": "https://fourzerotwo.si/mcp/v/web"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Web & domain tools'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 11 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.
