DomainProbe is a DNS and email authentication MCP server. Your assistant can audit a domain in one call, look up any record, check SPF, DKIM, DMARC, MTA-STS and BIMI, test whether a sending IP passes SPF, and write the DNS records 17 mail services need.
Paste a message's raw headers and it reads them like a postmaster: authentication and alignment, the sending server, every hop and its delay, spam scores and Gmail and Yahoo sender rules. It also finds registered look-alike domains that can receive mail, subdomains pointing at unclaimed cloud resources, blocklistings, certificates and certificate logs, HTTPS headers, DNSSEC and DNS propagation.
