What is A2A?
A2A (Agent-to-Agent) is an open protocol by Google that enables AI agents to communicate and collaborate with each other. It defines a standard way for agents to describe their capabilities and interact.
Every A2A agent serves a machine-readable “agent card” at a standard location, describing what it can do, what inputs it accepts, and how to interact with it.
