wwhois — MCP server

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.
  • Auth: none — public, read-only
  • Rate limit: 30 tool calls / minute per client IP
  • Docs: https://wwhois.ru/mcp

Connect

  "mcpServers": {
    "wwhois": { "type": "http", "url": "https://wwhois.ru/backend/mcp" }
  }

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.
