Domain Check

saidutt46/domain-check

A domain availability checker that connects to Claude via MCP and exposes batch RDAP/WHOIS lookups with pattern generation. You get tools for checking single domains, expanding names across TLD lists, using presets like "startup" or "tech", and generating permutations with prefix/suffix combinations. Useful when you're naming a project and want Claude to explore hundreds of options without manual grinding. The underlying Rust engine handles 1,200+ TLDs with concurrent checks and automatic protocol fallback. Returns structured results with registrar info, expiration dates, and availability status. Beats browser tab juggling when you need systematic domain research during early product work.
