Overview

DomainCat is an MCP server that monitors SSL certificates including origins behind Cloudflare, tracks domain expiry dates, checks DNS records, validates email authentication, and scans email blacklists. It lets AI assistants query domain health and security data as callable tools without switching between applications.

The server runs as a hosted remote endpoint at https://domaincat.app/api/mcp with no authentication required and nothing to install locally. Version v1.0.0 is the current release. Visit https://domaincat.app/docs for full documentation.

DomainCat is listed in the Communication category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain DomainCat, claim this listing to verify ownership and keep information up to date.
