What is Agent2Agent Protocol?
A2A (Agent2Agent) is an open protocol designed to enable interoperability among diverse AI agents built by various vendors and frameworks. It allows agents to discover each other, communicate asynchronously using HTTP and JSON-RPC, and execute collaborative tasks with secure, authenticated channels. The protocol supports real-time updates via server-sent events and push notifications, making it suitable for long-running, complex operations. A2A defines core objects such as Agent Card, Task, Message, Part, and Artifact to structure interactions. It is enterprise-ready with a focus on security, privacy, and scalability, fostering cross-platform automation and multi-agent ecosystems, useful for enterprise automation, research, and multi-agent system development.
