A2A

also Agent2Agent

An open protocol for agent-to-agent communication that lets independent AI agents from different vendors discover each other and collaborate on tasks.

Analogy

Like email standards between companies: different agents can message and work together because they share a common protocol.

Why it matters

A2A points toward automations where specialized agents from different platforms cooperate instead of being locked into one vendor.

In practice

A scheduling agent negotiating an appointment time directly with a separate customer-service agent.
