Show HN: I made an MCP Server to check whether domains are available
elgertam Thursday, July 03, 2025
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

This article provides an overview of the Whois RDAP MCP (Manifest Change Proposal) project, which aims to improve the way ICANN manages and distributes WHOIS data by leveraging blockchain technology and decentralized identity standards.
