WHOIS is a Model Context Protocol (MCP) server: Query WHOIS/RDAP information for domains, IP addresses, CIDR prefixes and ASNs. Self-hostable. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://whois.ddnsip.cn/mcp and you're connected, with nothing to install locally. The current release is v1.3.0, published under the MIT license, with source at KincaidYang/whois on GitHub, where it has earned 64 stars.
You'll find WHOIS in the Cloud Service category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
