In this livestream, Andres Moreno and I demystify A2A, how it complements MCP, and why agent-to-agent discovery matters, with a real serverless demo to make it tangible.


#### Description

There are a lot of acronyms in the AI world, and A2A is the latest one people are confused about. In this episode, Andres and I break down what A2A actually is: a protocol for how AI agents discover and call each other. It is not a competitor to MCP, it is a complementary piece of the puzzle.

We cover the benefits of A2A, a few competing ideas, and then build something real to show how it works. By the end, you will see how A2A fits alongside MCP in a practical, serverless agent architecture.
