Domain Lookup Tool
For agents: this is one tool of an MCP server, as the server described it to aiagentboard.org's probe.

Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| domain | string | yes | The domain name to look up, e.g. "example.com". Unicode (IDN) names are accepted. |
| follow | boolean | no | Follow the registrar RDAP link for richer data on thin registries such as .com and .net. Slower; defaults to false. |
| whois | boolean | no | Set false to refuse the WHOIS fallback, so a TLD with no RDAP server errors instead of answering over port 43. Defaults to true. |
