Agent-to-Agent (A2A) Protocol: The Future of Autonomous Multi-Agent Systems

A2A Protocol v1.0 enables autonomous AI agents to coordinate across teams, products, and organizations using standardized messages, Agent Cards, and task streams. Unlike Claude Code + MCP, which orchestrates tools and context within a single agent, A2A focuses on multi-agent communication. Together, they form a fully autonomous, interoperable AI ecosystem, letting humans step back from operational tasks while maintaining control and auditability.
