Tools

Tool	Arguments	Returns
whois_lookup	domain (string)	Registration state (registered / available / reserved / unsupported / unknown) and the full raw WHOIS/RDAP record: registrar, registration and expiry dates, name servers, status. 1400+ zones including IDN / Cyrillic (.рф, .москва). RDAP where a zone offers it, plain WHOIS otherwise.
ip_geolocation	ip (string)	Country, region, city, ISP and organisation for an IPv4/IPv6 address.
punycode_convert	value (string)	Converts a domain between Unicode (IDN) and Punycode/ACE (xn--), both directions, auto-detected.

Manual check

curl -s https://wwhois.ru/backend/mcp \
  -H 'Content-Type: application/json' -H 'Accept: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Notes

The server is a thin MCP wrapper over wwhois.ru's existing tools — the data is the same you get from the web pages at /whois, /ip and /punycode. It is a hosted remote service; this repository holds the description and manifests only.
