Overview

This MCP server allows AI agents like Claude Desktop, Cursor, Windsurf,.. etc to perform WHOIS lookups and retrieve domain details.

Purpose You can directly ask the AI to check if a domain is available, who owns it, when it was registered, and other important details. No need to go to browser and search.

What is a WHOIS Lookup? A WHOIS lookup is the process of querying a WHOIS database to retrieve registration details about a domain name, IP address, or autonomous system. It helps users find out who owns a domain, when it was registered, when it expires, and other important details.

What Information Can a WHOIS Lookup Provide?

When you perform a WHOIS lookup, you can retrieve details such as:

Domain Name – The specific domain queried
Registrar Name – The company managing the domain registration (e.g., GoDaddy, Namecheap)
Registrant Details – The name, organization, and contact details of the domain owner (unless protected by WHOIS privacy)
Registration & Expiry Date – When the domain was registered and when it will expire
Name Servers – The DNS servers the domain is using
Domain Status – Active, expired, locked, or pending deletion
Contact Information – Administrative, technical, and billing contacts (if not hidden)

Available Tools

Tool	Description
`whois_domain`	Looksup whois information about the domain
`whois_tld`	Looksup whois information about the Top Level Domain (TLD)
`whois_ip`	Looksup whois information about the IP
`whois_as`	Looksup whois information about the Autonomous System Number (ASN)

Using with Cursor

Installation - Globally

Run the MCP server using npx:

npx -y @bharathvaj/whois-mcp@latest

In your Cursor IDE

Go to Cursor Settings > MCP
Click + Add New MCP Server
Fill in the form:
- Name: Whois Lookup (or any name you prefer)
- Type: command
- Command: npx -y @bharathvaj/whois-mcp@latest

Installation - Project-specific

Add an .cursor/mcp.json file to your project:

{
  "mcpServers": {
    "whois": {
      "command": "npx",
      "args": [
        "-y",
        "@bharathvaj/whois-mcp@latest"
      ]
    }
  }
}

Usage

Once configured, the whois tools will be automatically available to the Cursor AI Agent. You can:

The tool will be listed under Available Tools in MCP settings
Agent will automatically use it when relevant
You can explicitly ask Agent to send notifications

Using with Roo Code

Access the MCP settings by clicking “Edit MCP Settings” in Roo Code settings or using the “Roo Code: Open MCP Config” command in VS Code's command palette.

{
  "mcpServers": {
    "whois": {
      "command": "npx",
      "args": [
        "-y",
        "@bharathvaj/whois-mcp@latest"
      ]
