What it does

This server checks email authentication configuration (SPF, DKIM, DMARC, MX records) for a domain and returns a grade with a shareable report URL. It is for developers and domain administrators who need to verify email deliverability setup without signup or API keys.

  • Check whether a domain is properly configured to prevent email spoofing and get a shareable report to send to whoever manages DNS.
  • Verify SPF, DKIM, and DMARC records are correctly set up, including detection of RFC 7208 lookup limit violations that break SPF.
  • Audit MX and null-MX records to ensure email delivery is properly configured.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
