# rdap-mcp-server

[Model Context Protocol](https://modelcontextprotocol.io) server to look up domain names and IPs using [RDAP](https://www.icann.org/rdap).

This project is forked from [whois-mcp](https://github.com/bharathvaj-ganesan/whois-mcp).
Some TLDs such as .dev no longer support the whois protocol, but do support RDAP.
