Overview
Agent2Agent (A2A) is an open protocol designed to enable communication and interoperability among diverse agent applications. It addresses the challenge in the AI field where general-purpose AI agents developed by different companies using various frameworks struggle to effectively communicate and collaborate. Through A2A, these agents can discover each other's capabilities, negotiate interaction modes (such as text, forms, or media), securely cooperate on long-term tasks, and do so without exposing their internal states, memories, or tools.
Key features
- ▪Facilitates communication between different AI agents
- ▪Supports multiple interaction modes
- ▪Ensures secure collaboration for long-term tasks
- ▪Protects internal agent information
