Google’s Agent2Agent (A2A) is a brand new protocol to facilitate communication between independent AI agents—but what does this actually mean?

Imagine waking up to a push notification that your fridge has been restocked, your flight’s been rerouted around bad weather, and your taxes were filed—all while you were sleeping. No apps. No tabs. Just invisible agents handling your life. Sounds futuristic? In this episode of In The Loop, I dig into what could make that scenario a reality: Google’s new Agent-to-Agent protocol, or A2A.

This isn’t just a nerdy dive into AI plumbing—this is the foundation that might define how AI agents talk, collaborate, and make your digital life seamless. We explore why A2A could become the “HTTP for AI,” how it works with the Model-Context Protocol (MCP), and why it matters for developers, companies, and, yep, even governments. If you're building in the AI space or just fascinated by how the future gets built, you’re gonna want to listen to this.
