What is the Agent2Agent (A2A) protocol?

A2A's an open standard for AI agents to discover each other, exchange messages, and coordinate tasks across different frameworks and vendors using web tech like HTTP and JSON.

How does A2A differ from MCP?

MCP connects agents to tools and data; A2A handles agent-to-agent comms. They stack for complete systems.

Will Agent2Agent make multi-agent AI scalable?

Yes, by standardizing coordination, cutting custom integrations, and enabling modular agent networks — if adoption sticks.
