Whois, Dns, Ssl, And Domain Availability Lookups For Ai Assistants

Created By

Whoisjsona month ago

WhoisJSON MCP Server exposes four domain intelligence tools directly inside Claude, Cursor, and Windsurf — no code required. whois_lookup: Full WHOIS registration record for any domain — registrar, creation and expiry dates, nameservers, registrant contacts, and DNSSEC status. dns_lookup: All DNS records in a single call — A, AAAA, MX, TXT, CNAME, NS, SOA, CAA, DMARC, and more. Useful for mail server audits, SPF/DKIM verification, and infrastructure mapping. ssl_check: TLS certificate details including issuer, expiry date, Subject Alternative Names, and full chain validity. Detect expired or misconfigured certificates instantly. domain_availability: Instant registration availability check for any TLD. Returns a clear registered/available status. Your WhoisJSON API key works identically for the REST API and the MCP server. 1,000 free requests/month, no credit card required. Get your API key at whoisjson.com.
