Domain Checker Mcp

Exposes three tools for checking domain availability through Claude: check_domains for full DNS and RDAP/WHOIS verification, check_names to test base names across multiple TLDs automatically, and check_domains_quick for DNS-only speed checks. Built by Brave Labs, it handles up to 100 domains in parallel with batched verification queries. The hybrid approach runs fast DNS lookups first, then confirms availability through RDAP with WHOIS fallback by pulling from IANA's bootstrap registry. Responses include summary stats and separate lists for available, taken, and errored domains. Reach for this when you're brainstorming project names or need to verify domain availability without leaving your Claude conversation.
