dossier_dmarc
shallowcom.domainposture/mcp · Verify this server
Core dossier check: Retrieve and parse a domain's DMARC policy from its _dmarc.<domain> TXT record, returning all tags. Use to audit email authentication policy, verify the p (policy) and rua (reporting) settings, or confirm alignment mode; pair with dossier_spf and dossier_dkim for complete email-auth coverage. Queries _dmarc.<domain> via Cloudflare DoH (1.1.1.1), 5 s timeout; parses each tag=value pair. Returns a CheckResult: on success, {status:"ok", raw, tags:{p, rua, ruf, adkim, aspf,...}}; on failure, {status:"error", reason}.
