Queries RDAP registries directly to check domain availability without scraping or API keys. Exposes three tools: check single domains, bulk check up to 50 at once, or generate smart suggestions from keywords that return variations across .com, .io, .ai, .dev, and .co with common prefixes. Uses Verisign RDAP for .com/.net, PIR for .org, and rdap.org for everything else. Runs as a remote server on Fly.dev so there's nothing to install locally. Useful when you're naming a project, validating user input for domain fields, or building registration flows. Also works as a standalone REST API with OpenAPI docs if you need it outside MCP contexts.
