Why it worked

The video explains a significant shift in AI development (MCP and A2A) announced by a major tech company (Google), tapping into the current interest in AI advancements and offering a clear, concise explanation of a complex topic.

Summary

Google announced the Agent to Agent (A2A) protocol, which works with the Model Context Protocol (MCP). This shift allows AI systems to use tools by describing them, rather than being explicitly programmed for every step, fundamentally changing software development.

Product placement

MCP (Model Context Protocol) ACTS - it is a protocol that allows AI systems to work with tools, and it is explained in the video. Removing it would change the video's explanation. A2A (Agent to Agent) ACTS - it is a protocol announced by Google that connects to MCP. Removing it would change the video's explanation. Google ACTS - it announced A2A. Removing it would change the video's explanation. Substack APPEARS - it is a platform where the creator wrote a deep dive on MCP. Removing it would not change the video's explanation.

Transcript

Hey, I'm back. There's another new AI thing to talk about. Lol. So what happened today was that Google announced A2A, an agent to agent protocol, and it connects to something I've been obsessing over lately, which is MCP or Model Context Protocol. They both are protocols. I'll explain what I mean. First, let me back up. I wrote a deep dive on Substack about Model Context Protocol, totally free. It's fundamentally like, don't have to go read it. I'll explain it right here. It's a fascinating shift in how AI systems work with tools because before for 70 years, we would program exactly what we wanted AI to do. And now we let AI decide what to do. And so what we mean by that is that instead of programming every step in a workflow, Model Context Protocol allows us to describe tools and lets AI figure out how to use those tools. So think about that. Instead of writing specific instructions, if this happens, use you're just saying here are all the tools available and you figure it out. You reason.
