Web + MCP beta

Domain health, interpreted.

Domain Health AI checks a domain against published standards and returns what to fix — findings and exact action items. security.txt (RFC 9116) verified down to its OpenPGP signature, plus the SPF, DKIM, and DMARC email-auth posture.

Account features — check history, daily monitoring — are free while Domain Health AI is in beta.

This site publishes its own security.txt

Under the hood

Four checks — security-txt, spf, dkim, dmarc — adjudicated against the domain's detected role, anchored at the apex, run from this page or from any MCP client. The full catalog, what a report carries, and a specimen report.
