DNS MCP Server

A community-driven MCP server providing real-time DNS security analysis for AI assistants. It enables SOC-style investigations by performing DNSSEC chain validation, checking email authentication postures (SPF, DKIM, DMARC, DANE, BIMI), and querying RDAP registration intelligence. The server exposes tools for standard DNS lookups, NSEC/NSEC3 analysis, and user identity verification via OAuth.
