TamingDNS MCP server: 19 DNS/email tools that return verdicts, not raw records
TamingTech · reddit · 2026-11-12
A developer built a remote MCP server (read-only, no auth, streamable HTTP) for DNS and email deliverability checks. Core design: instead of handing models raw DMARC records to guess at, every tool returns a uniform envelope — status, verdict, grade, and findings with stable codes the agent can report. 19 tools cover SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI, DANE, DNSSEC, propagation across 14 resolvers, M365/Workspace audits, header analysis, bounce decoding and more. Sample results: google.com grade A; example.org warns RUAMISSINGUNDERENFORCEMENT; iana.org grade D POLICYNONE. Timeouts return retriable errors, never 'no record found'. Listed in the official MCP registry.
