## Tools (as reported by the server, not verified)

- `check\_certificate`: Check one domain's TLS certificate and return a verdict: status OK \| WARN \| CRITICAL \| UNKNOWN, judged from the certificate chain the server actually serves. Measured from Korean point A \(full chain and CRL revocation\) plus Korean point B and an overseas point on the Globalping public measurement ne
- `check\_expiry`: Verdict for up to 5 domains at once: status OK \| WARN \| CRITICAL \| UNKNOWN per domain combining the served certificate \(verification, days left, null when the server cannot be measured\) and domain registration expiry \(RDAP\), plus Korean alert lines. Use this for inventories, CI gates \(fail unless st
- `check\_security`: Security posture check of a web server \(no port scanning\): TLS protocol support \(legacy 1.0/1.1 detection via a Korean network probe\), security headers \(HSTS/CSP/X-Content-Type-Options/anti-clickjacking/Referrer-Policy\), HTTP→HTTPS redirect, and certificate key/signature strength. Returns per-item p
- `check\_dns`: DNS and hosting facts for a domain: nameservers with DNS provider, A/AAAA with IP owner \(ASN\), CNAME, MX, CAA \(which CAs may issue\), SPF/DMARC, DNSSEC, registrar and domain expiry \(RDAP\).
- `check\_dns\_propagation`: Compare answers for one DNS record across resolvers: the authoritative nameservers, Korean ISPs \(KT, SK Broadband, LG U+\) and public resolvers \(Cloudflare, Google, Quad9, OpenDNS\), measured from a Korean network. Use it to confirm a TXT/CNAME for certificate domain validation \(e.g. \_acme-challenge\)
- `explain\_tls\_error`: Explain a TLS/SSL certificate error message from a browser, curl/OpenSSL, Java, Python, Node.js, Go or .NET: likely causes, fixes, and links to step-by-step guides \(Korean\). Works offline from a curated knowledge base.
- `watch\_expiry`: Subscribe an email address to free daily expiry monitoring of up to 5 domains \(certificate, domain registration and security grade\) with email alerts, plus an optional Slack/Discord/Telegram/webhook channel. Also alerts when Certificate Transparency logs show a new certificate for a domain from a CA
