FAQ from Whodis MCP Server

What does the `check-domain-availability` tool output?

It returns a JSON object with two arrays: available (domains that appear unregistered) and unavailable (domains that appear registered). Domains where the lookup failed are omitted.

How accurate are the domain checks?

Accuracy depends on WHOIS server responses and may not be 100% reliable for all TLDs or due to temporary network issues. The server cannot guarantee correctness for every lookup.

What are the prerequisites to run this server?

Node.js (version 18.x or higher) and Git are required.

How can I test the tool locally?

Start the development server with npm run dev:server, then open the MCP Inspector at http://localhost:5173 in your browser. You can also test via the CLI using npm run dev:cli -- check-domain-availability <domains...>.
