A hosted, read-only MCP service for WHOIS/RDAP domain lookups, IP geolocation and Punycode conversion, with no API key required.
What you can do
Look up a domain's registration state and full raw WHOIS/RDAP record, including registrar, dates, name servers and status, across 1400+ zones including IDN/Cyrillic ones. Geolocate an IPv4 or IPv6 address to country, region, city, ISP and organisation. Convert a domain between Unicode (IDN) and Punycode/ACE form in either direction, auto-detected.
When to use it
Useful when an assistant needs to check whether a domain is registered or available, inspect registrar and expiry details, identify where an IP address is located, or convert internationalized domain names for DNS or web work.
Requirements
A remote Streamable HTTP endpoint; no installation, account or API key. The client must support remote MCP servers over HTTP. Rate limited to 30 tool calls per minute per client IP.
Before you install
Read-only and public, but every lookup goes to the third-party wwhois.ru service, so queried domains and IP addresses are visible to it. Results are only as current as that service's data.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/ru.wwhois%2Fwhois-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
WHOIS/RDAP domain lookup, IP geolocation and Punycode conversion, exposed as
Model Context Protocol tools. Backed by
wwhois.ru.
Server URL:https://wwhois.ru/backend/mcp
Transport: Streamable HTTP (JSON-RPC 2.0)
Protocol revisions:2026-07-28 (current — per-request metadata,
server/discover) and 2025-11-25 … 2024-11-05 (the initialize
handshake). Both are served on the same endpoint; the server picks by how
the client opens.
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.
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.
Look up WHOIS/RDAP data for a domain: registration state (registered / available / reserved / unsupported / unknown) and the full raw registry record (registrar, dates, name servers, status). Supports 1400+ zones including IDN / Cyrillic domains.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
