It started with a stupid habit 🫠 Every morning (or even during the day) I'd open a news channel to check one thing - some specific topic I actually cared about. Twenty minutes later I'd be three threads deep into something completely unrelated, mildly annoyed at myself, and no closer to the thing I opened the app for Telegram has no keyword alerts (as far as I know).

The Model Context Protocol has transformed how we connect AI to tools. But connecting agents to tools is only half the battle — connecting agents to each other is where the real challenge begins. I recently read @raviteja_nekkalapu_'s excellent article "I built an AI security Firewall and made it open source because production apps were leaking SSNs to OpenAI" and it resonated deeply with challeng
