My own app, it's called Telosnex.
Unfortunately, the current available version doesn't have the agent stuff yet.
Hopefully in a week, realistically two.
I had the existing client app I've released-but-not-released-out-loud. Couple days before Christmas, for fun, I spent a couple hours wiring up the Anthropic Model Context Protocol filesystem server example. Within an hour it was clear this was special and I needed to get it out ASAP. Stunning stuff in action.
