Connect Claude & ChatGPT to WhoisFreaks

Ask your AI who a domain is registered to, when it expires, or which mail servers it uses, and get the answer from WhoisFreaks. It can read live and historical WHOIS and DNS records, SSL certificates, subdomains, IP geolocation and reputation, and check whether a domain is free to register. It can also run reverse WHOIS and reverse DNS searches and find typosquatting domains.

Questions

What can the AI do in WhoisFreaks?

It can look up live and historical WHOIS and DNS records, WHOIS for IP addresses and ASNs, SSL certificates, subdomains, IP geolocation and IP and domain reputation. It can check domain availability, find typosquatting domains, run reverse WHOIS and reverse DNS searches and check your API credit usage. All tools read data. None of them change anything.

Does the AI see my WhoisFreaks credentials?

No. Your WhoisFreaks API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on. Broad searches like reverse WHOIS and reverse DNS can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own WhoisFreaks account. Lookups use API credits on that account.

Do lookups use WhoisFreaks credits?

Yes. Every lookup uses API credits on your WhoisFreaks account. The AI can check your credit usage with the get_account_usage tool, so you can simply ask how many credits you have used.
