What is Agent2Agent A2A protocol ?

A2A is an open standard for agents to communicate — discover, delegate, stream results — across frameworks. Think MCP but for agent-to-agent, not tools.

Does Agent2Agent replace MCP?

No. MCP handles tools/data; A2A handles collaboration. They're layers in the same stack.

Will A2A work with my multi-agent framework?

By 2026, major players are aligning. Check LangChain, CrewAI integrations — adoption's accelerating under Linux Foundation.
