Domain Checker

概要

The Domain Checker MCP Server provides a rapid and precise solution for verifying domain name availability. It employs a hybrid approach, initially performing a quick DNS lookup and then conducting thorough RDAP (with WHOIS fallback) verification for domains that appear available, ensuring high accuracy. Designed for efficiency, it supports bulk checks of up to 100 domains in parallel, automatic name expansion across popular TLDs, and flexible filtering of results, making it an indispensable tool for developers and businesses managing web assets. It integrates seamlessly with Model Context Protocol (MCP) clients like Claude Desktop and Claude Code.
