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)
