Domain Check

Domain Check is an MCP server that provides fast, programmatic domain availability checking across 1,200+ TLDs, supporting both RDAP and WHOIS protocols. It exposes tools for AI agents and assistants to perform bulk/batch domain lookups, domain status audits, TLD-specific checks, registrar data retrieval, pattern-based name generation, and use of curated domain presets for scenarios like startup naming or brand protection. It integrates with MCP-compatible AI clients (e.g. Claude, Cursor, Copilot) and is useful for developers, brand managers, entrepreneurs, marketers, and anyone needing scalable, automated domain search and validation via agent workflows.
