Compare
Using WhoisXML directly versus through looot
Only the looot side is filled in. Check the provider's docs for the direct side.
| WhoisXML directly | Through looot | |
|---|---|---|
| Account | Gap. Check the provider's docs | Yes. One looot sign-in. You do not set up a separate WhoisXML account. |
| Price | Gap. Check the provider's docs | Yes. Per call, shown before the run. |
| Finding the endpoint | Gap. Check the provider's docs | Yes. Your agent searches the looot catalog for the task. |
| Other providers | Gap. Check the provider's docs | Yes. The same connection reaches every provider in the catalog. |
FAQ
WhoisXML MCP, answered
looot is not a server made by WhoisXML. looot is one MCP connection that reaches WhoisXML and every other provider in the catalog, billed per call. Check WhoisXML's docs for a server of its own.
Add the looot MCP connection to Claude Code once, using the setup at https://looot.ai/skill.md. Then ask Claude Code to use looot for the job. WhoisXML is one of the providers behind looot; your agent calls its endpoints through the looot MCP connection.
Add the looot MCP connection in Cursor's MCP settings, then ask the agent to use looot. WhoisXML is one of the providers behind looot; your agent calls its endpoints through the looot MCP connection.
It works in any client that can add an MCP connection. Where your ChatGPT plan lets you add one, add looot and ask it to use looot. WhoisXML is one of the providers behind looot; your agent calls its endpoints through the looot MCP connection.
The jobs on this page: whois record for a domain, dns records for a domain, subdomains of a domain, check if a domain is available, locate an ip address, verify an email address. The page marks any job whose endpoints are not in the live catalog.
You pay per call. The price of each endpoint is shown before you run it, so your agent can check it first and pick the cheapest one that fits.
You connect to looot, not to WhoisXML. looot makes the provider call for you and bills each call at the price shown before the run.
It searches the looot catalog for the task, reads the endpoint's parameters and price, and then calls it. You do not have to read WhoisXML's docs first.
Providers that often go with WhoisXML are BuiltWith, DataForSEO, Context.dev, ZeroBounce. All of them sit behind the same looot MCP connection.
Yes. The free WHOIS lookup at /free-tools/whois-lookup and the domain availability checker at /free-tools/domain-availability-checker run the same WhoisXML endpoints in your browser. Use the MCP connection when your agent needs many lookups or wants to act on the answer.
Many WHOIS records are redacted for privacy, so the owner's name and email are often hidden; the registrar and dates usually remain. The catalog does not run WhoisXML's historical WHOIS or reverse WHOIS search today, and an IP lookup gives a network location, not a street address.
