概览

What is Whois MCP?

Whois MCP is a Model Context Protocol (MCP) server that allows AI agents—such as Claude Desktop, Cursor, and Windsurf—to perform WHOIS lookups and retrieve domain registration details, including ownership, registration and expiry dates, registrar information, name servers, and domain status.

How to use Whois MCP?

Configure the server as an MCP tool using the command npx -y @bharathvaj/whois-mcp@latest in supported IDEs (Cursor, VS Code with Roo Code) or any MCP-compatible client. Once added, the AI agent automatically gains access to four tools: whois_domain, whois_tld, whois_ip, and whois_as.

Key features of Whois MCP

  • Perform WHOIS lookups directly from AI agents.
  • Retrieve domain, TLD, IP, and ASN information.
  • No browser or terminal needed—just ask the AI.
  • Easy installation via npx with no API keys required.
  • Compatible with Claude Desktop, Cursor, Windsurf, Roo Code.
  • Provides registration, expiry, registrar, and name server details.

Use cases of Whois MCP

  • Check if a domain is available for registration.
  • Find out who owns a domain and when it was registered.
  • Look up the expiry date or status of a domain.
  • Investigate IP addresses and autonomous system numbers.
  • Automate domain research within AI-powered workflows.

常见问题

1

What runtime or dependencies does Whois MCP require?

The server runs on Node.js and is invoked via `npx` (included with Node). No additional dependencies or API keys are needed.

2

Where does the WHOIS data come from?

All lookups query public WHOIS databases directly; no data is stored by the server. Results depend on the registrar and privacy settings of the queried resource.

3

How is Whois MCP connected to the AI client?

It uses the standard MCP stdio transport—the server runs as a command-line process and communicates via stdin/stdout. No network server or authentication is involved.

4

Can I use Whois MCP in custom projects?

Yes. The server can be integrated with any MCP-compatible client (Claude Desktop, Cursor, VS Code with Roo Code) by adding a JSON configuration with the `npx` command.

5

What types of lookups are supported?

The `whois_domain` tool provides domain registration details; `whois_tld` queries top-level domain information; `whois_ip` looks up IP addresses; and `whois_as` retrieves ASN details.
