I expected Defender to find Claude Code and maybe Cursor. It found 8 AI agents across 2 lab devices. Apparently, my endpoints were running a small bed-and-breakfast. I dug into the inventory, MCP servers, AgentsInfo, licensing, and runtime protection: getrubix.com/blog/discove...

I used Claude for this one. I will say it did still take some time. The first version was good, but I made constant tweaks along the way. I like being able to ask "why" it's doing it that way. It helped me a lot in learning processes.
