dsh-whois-plugin

When an agent needs to look up domain registration details, the old route means port-43 text parsing or shelling out to a whois binary—clunky and hard to make cross-platform. dsh-whois-plugin collapses that into a single structured tool call: the model passes a domain, and the plugin resolves the authoritative RDAP server from IANA's bootstrap registry, queries it over HTTPS, and returns clean JSON covering registrar, domain status, registration and expiration dates, nameservers, and registrant entities where the registry publishes them.

No API key, no external binary, no manual endpoint configuration. The plugin caches the IANA bootstrap table for 24 hours and routes each TLD to its correct server automatically. For ccTLDs that have not yet published an RDAP entry, it throws a clear error instead of silently falling back to the legacy WHOIS protocol.

It fits workflows that repeatedly need domain intelligence: security researchers tracking registration changes and registrar shifts, DevOps engineers confirming DNS ownership during incident response, or any developer who wants to ask an agent a plain-language question and get back authoritative, structured registration data.
