A2A Protocol (Agent2Agent) Explained: How AI Agents Collaborate
The A to A protocol, introduced by Google and now open source under the Linux Foundation, standardizes communication and collaboration between AI agents, enabling them to solve complex problems by integrating multiple agents, such as in travel planning, through a structured process involving discovery, authentication, and communication.
MAIN POINTS FROM TRANSCRIPT
- AI agents are autonomous systems that perceive, decide, and act to achieve goals.
- The A to A protocol standardizes AI agent communication and collaboration.
- Introduced by Google in 2025, A to A is now open source under the Linux Foundation.
- The protocol involves discovery, authentication, and communication stages for agent interaction.
TAKEAWAYS
- AI agents can integrate for complex problem-solving, like travel planning.
- A to A protocol allows using third-party agents without knowing their internal workings.
- Client and remote agents communicate using the A to A protocol.
- Agent cards provide identity and capability information for discovery.
