About

DmarcDkim.com provides a hosted MCP server for DNS and email authentication validation, enabling developers to programmatically verify DMARC, SPF, and DKIM configurations. The server offers four core tools: DNS lookup for querying A, AAAA, MX, TXT, NS, CNAME, PTR records and WHOIS data; DMARC checking with error detection; SPF validation with RFC 7208 compliance checking and circular reference detection; and SPF merge functionality to consolidate multiple SPF records into optimized single records. Built for email security professionals and developers managing domain authentication, the service helps prevent email spoofing, improve deliverability, and ensure email authentication compliance.
