Windsurf Mail Security Tools check_domain_email_security

How to: Windsurf Mail Security Tools check_domain_email_security

client:Windsurf transport:streamable-http tool:check_domain_email_security

Add Mail Security Tools to Windsurf

  1. 01

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

{
  "mcpServers": {
    "email-security": {
      "serverUrl": "https://api.mailsecuritytools.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Mail Security 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 14 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.
