A2A Protocol (Agent2Agent)
Open standard for AI agent interoperability enabling seamless collaboration across platforms
In 30 seconds
- What
- Agents discover each other's capabilities via standardized cards, then exchange messages with task IDs to coordinate work across platforms.
- When to use
- Multiple independent agents from different systems need to collaborate on long-running tasks with real-time state synchronization.
- Watch out
- High implementation complexity and operational overhead often outweigh benefits unless you genuinely need cross-platform interoperability at scale.
