DomainCheckr provides an effortless way to verify domain name availability in real-time, leveraging the RDAP protocol, the contemporary successor to WHOIS. Designed as a remote MCP server, it integrates seamlessly with popular AI assistant clients like Claude, Cursor, and Windsurf, requiring no local installation or API keys. It offers functionalities for checking individual domains, performing bulk checks for up to 50 domains, and generating creative domain name suggestions based on keywords. The service operates by querying domain registries directly, ensuring accurate and up-to-date results, and is also exposed as a versatile REST API for broader integration.
