Connects to Claude via stdio and exposes four domain availability tools: check_domains for exact lookups, check_brand_domains to test one name across 17+ TLDs at once, suggest_and_check_domains to generate variations from keywords and batch-check them, and list_supported_tlds. Uses DNS lookups plus WHOIS queries under the hood, no API keys needed. Supports 30+ TLDs including .com, .io, .ai, .dev, and trending options like .gg and .so. Ships with an optional brand-naming skill for Claude Code that guides you through the full naming workflow. Reach for this when you're brainstorming product names and want to filter out taken domains in real time instead of tab-switching to a registrar every 30 seconds.
