WhoisLookup is a Model Context Protocol (MCP) server: Domain WHOIS, DNS records, SSL certificates, and availability checks. Because it speaks the Model Context Protocol, AI assistants can use WhoisLookup as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://whois.rjctdlabs.xyz/sse and you're connected, with nothing to install locally. The current release is v1.0.0.
On mcp.site, WhoisLookup sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
