A2A Protocol (Agent-to-Agent)

A2A is an open protocol for seamless communication and collaboration between AI agents, regardless of their underlying frameworks or vendors. Originally created by Google and now under the Linux Foundation, it enables agents to discover each other via agent cards, exchange messages through JSON-RPC/gRPC/HTTP bindings, and manage long-running tasks with streaming and push notification support. A2A is complementary to MCP - while MCP connects models to tools and data, A2A enables agent-to-agent collaboration where agents remain autonomous entities.
