Whois, Dns, Ssl, And Domain Availability Lookups For Ai Assistants MCP Server のツール

Retrieve WHOIS registration data for a domain name. Returns registrar details, creation/expiration dates, nameservers, contact information, DNSSEC status, and domain age analysis. Useful for checking domain ownership and registration info.

Query DNS records for a domain name. Returns all available record types including A (IPv4), AAAA (IPv6), MX (mail), NS (nameservers), TXT, CNAME, SOA, CAA, DMARC, BIMI, MTA-STS, and TLS-RPT records. Useful for diagnosing DNS configuration, verifying mail settings, or auditing domain infrastructure.

Retrieve and validate the SSL/TLS certificate details for a domain. Returns the issuer, validity period (valid_from / valid_to), whether the certificate is currently valid, fingerprints, subject alternative names, and full certificate details. Useful for checking certificate expiry, verifying the issuer, or auditing TLS configuration.

Check whether a domain name is available for registration. Returns a boolean indicating if the domain is available. Useful for finding an unregistered domain before attempting to register it.
