Ask Claude When Your Certs Expire

DomainCat has a built-in MCP server, so Claude, Cursor, VS Code and other AI assistants can read (and, if you allow it, manage) your domain and SSL monitoring. Ask in plain English and get answers from your real data.

What You Can Ask

Once connected, your assistant can answer questions like these from DomainCat's live monitoring data:

"Which SSL certificates expire in the next 30 days?"
"Is the origin cert behind Cloudflare OK on shop.example.com?"
"Are any of my domains on a blacklist right now?"
"Give me a one-line health summary of every client in the Acme group."
"Add these 12 domains to the Acme group and tag them prod." (needs a read + write connection)

What Is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants use outside tools safely. Instead of copying and pasting a dashboard into a chat, the assistant calls DomainCat directly and gets the exact numbers, with only the access you granted.

DomainCat runs a remote MCP server at https://domaincat.app/api/mcp (Streamable HTTP). It's listed in Claude's connector directory and the official MCP Registry as app.domaincat/domaincat.
