What is Agent2Agent protocol?

A2A's an open standard for AI agents to discover, negotiate, and collaborate across different systems, clouds, and companies using web tech like HTTP and JSON-RPC.

How does A2A differ from MCP?

MCP connects agents to their tools and data; A2A links agents to other agents for external teamwork.

Is Agent2Agent production-ready in 2026?

Yes, with Linux Foundation backing, multi-cloud support, and growing SDKs — but test cross-org flows first.
