Agent-to-Agent Protocol
A communication standard that lets AI agents from different vendors or runtimes interoperate.
What is Agent-to-Agent Protocol?
Agent-to-agent protocols (like Google's A2A) define how agents discover each other's capabilities, delegate sub-tasks, and exchange structured results across organisational or platform boundaries. Without a protocol, every agent-to-agent integration is a bespoke point-to-point bridge. See Agent-to-Agent Protocol.
