Claude connectorCommunityCheck DNS, email authentication, blocklists and TLS for any domain, with the fix for each finding.
Ask about a domain in plain words and Claude runs the checks against live DNS: records and propagation across five public resolvers, DNSSEC, SPF/DKIM/DMARC, mail blocklists, WHOIS/RDAP, TLS certificates and HTTP security headers. Every finding comes with a level, a plain explanation and, where there is one, the fix, so you get what to change rather than raw output.
All tools are read-only and need no account or key. Private and local addresses are refused. The audit prompt runs every check on a domain and lists what to fix, worst first.
