This Whois MCP server enables AI agents to perform WHOIS lookups to retrieve domain details directly inside your workflows. It supports checking domain availability, ownership, registration dates, name servers, and related information without leaving your AI environment.

How to use

You can access the WHOIS capabilities from your MCP-enabled AI agents. After configuring the MCP server, the available tools will appear under Tools, and your agent will automatically pick them up when a domain-related task is detected. You can also explicitly ask the agent to perform a WHOIS lookup for a specific domain to get details such as registrar, registration date, expiry, and name servers.

How to install

Prerequisites: Ensure you have Node.js and npm installed on your machine.”},{

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

Additional configuration notes

Global and project-specific installation methods are provided so you can run the MCP server either as a global tool or within a project. The global approach runs the MCP server via npx, while the project-specific approach embeds the MCP config in your project under .cursor/mcp.json.

Security and usage notes

Do not expose the MCP server to untrusted networks. Use standard access controls and monitor usage to prevent abuse of WHOIS lookups. If you plan to run the service in production, consider rate limiting and auditing lookup requests.
