Mcp Ip2whois

ip2whois/mcp-ip2whois

Connects Claude to the IP2WHOIS API for domain registration lookups and reverse IP searches. Exposes two main operations: get_whois pulls complete WHOIS records including registrar details, nameservers, expiry dates, and registrant info for any domain, while get_hosted_domains returns all domains hosted on a given IP address. Requires an API key from IP2Location.io, which gives you 500 free queries monthly. Reach for this when you need Claude to check domain ownership, verify registration status, investigate who's behind a website, or see what else is sharing hosting infrastructure. Built on FastMCP and runs via uvx, so setup is straightforward if you already have the MCP toolchain installed.
