About This MCP Server
1. DNS Check (Fast) - All domains are checked via DNS in parallel. If DNS resolves, the domain is definitely taken.
2. RDAP/WHOIS Verification (Accurate) - Domains that pass DNS (no records found) are verified via RDAP (preferred) or WHOIS (fallback) to confirm availability. RDAP servers are loaded dynamically from the IANA bootstrap registry.
3. Parallel Processing - Verification queries run in parallel batches of 20 for optimal throughput.
This hybrid approach gives you the speed of DNS checking with the accuracy of RDAP/WHOIS verification.
