What it looks like

You describe the business. Claude calls the tools, reads the results back and saves what you keep. A scripted walk-through of the real thing.

Claude
A scripted conversation, not a live session: Claude is asked for a name, calls generate_domains and search_domains over MCP, reads the availability back and then calls save_domain to keep two of them. The tool names and the shape of the results are the ones the server really returns.

The tools

11 of them, each backed by an endpoint the site already uses. One finds names, and the rest aim it at what you care about and keep what you found.

All of them need an account. The server connects as you, not as the public.

Full reference
search_domainsPrimary tool

Availability for any name across 1,400 extensions, in milliseconds, from daily registry data. Everything else on this page exists to point it at the right names and keep what it finds.

The same tools, in the browser

Every tool above wraps something you can use right now. The MCP server changes where you drive it from, not what it does.
