Google's Agent2Agent (A2A) Protocol is a new open standard that enables AI agents from different frameworks to communicate and collaborate seamlessly. Unlike existing orchestration frameworks that work within single ecosystems, A2A acts as a universal translator using JSON-RPC over HTTP, allowing agents to discover each other's capabilities through Agent Cards, exchange tasks, and coordinate work while maintaining their independence. The protocol complements tools like Anthropic's MCP by focusing on agent-to-agent communication rather than tool integration, and is backed by 50+ tech companies aiming to create an interoperable AI ecosystem.
