WhoisFreaks MCP Server
A Model Context Protocol (MCP) server that exposes the full WhoisFreaks API suite as AI-callable tools. Works with Claude Desktop, Cursor, Windsurf, VS Code, Continue, Zed, and any other MCP-compatible AI client.
Three ways to use it — pick what fits your setup:
| Method | Requires | Best for | |
|---|---|---|---|
| ⭐ Easiest | Hosted server | Just your API key | Everyone — nothing to install |
| Docker (pre-built image) | Docker | Running it on your own machine or VM | |
| Build from source | Java 17 + Maven | Contributors / custom builds |
Connect it to any MCP client via Streamable HTTP (/mcp endpoint, hosted or self-hosted) or stdio (local).
Every user brings their own WhoisFreaks API key — the HTTP server stores no key of its own and uses the key sent with each request.
