Show HN: I made an MCP Server to check whether domains are available (github.com)

I'm terrible at naming things, so I ask Claude & ChatGPT to help me make domain names. Unfortunately, the chatbots lack the tools to query Whois or RDAP, and instead use web search. This has a lot of false negatives & could even risks certain less ethical registrars front-running the queried names if they don't exist.

Thus I fired up Replit and guided it to a working model context protocol (MCP) server that can query for domain names using RDAP and Whois. I built caching in to be respectful of the servers. It works and has really sped up my ability to find good domains
