What is the Agent2Agent protocol?

A2A is an open standard launched by Google in 2025 for AI agents to discover, communicate, and coordinate across vendors using HTTP, JSON-RPC, and streaming.

Does Agent2Agent replace frameworks like LangChain?

No—it complements them. A2A handles inter-agent talk; frameworks manage internal logic and tools.

Can I use A2A in production today?

Yes, SDKs are available. Start with capability registries for discovery, test handoffs in sims before scaling.
