MCP + A2A agent that diagnoses a domain's DNS, TLS/SSL, HTTP, and email configuration from live probes and returns a short, prioritized report. Use for automated incident response (an external hostname suddenly unreachable, DNSSEC validation failure, DANE/TLSA mismatch), or for manual checks: a site that will not load, SSL certificate errors, email deliverability problems, or verifying configuration after a change.
