The Agent2Agent Protocol (A2A) (developers.googleblog.com)

Article summary

Google has introduced the Agent2Agent Protocol (A2A), an open protocol that enables AI agents to communicate and collaborate with each other, regardless of the underlying framework or vendor. A2A allows agents to securely exchange information, coordinate actions, and work across various enterprise platforms or applications. The protocol is designed to support enterprise-grade authentication and authorization, and is built on top of existing standards such as HTTP, SSE, and JSON-RPC. A2A has the potential to unlock a new era of agent interoperability, fostering innovation and creating more powerful and versatile agentic systems.

What commenters say

• The A2A protocol is not clearly explained, making it difficult to understand how it works and how to implement it.
• The protocol is unnecessary and existing standards such as REST and HTTP could be used instead.
• A2A is a step towards creating a new ecosystem of free programs that corporations can use to extract value without writing safety guards themselves.
• The protocol's use of multiple transport methods, including HTTP, SSE, and websockets, adds complexity and irrelevant baggage.
• The A2A protocol is a capabilities protocol that uses multiple transport protocols, making it more flexible and powerful than existing standards.
• The protocol's focus on agent interoperability and collaboration has the potential to unlock new possibilities for AI applications.
• The use of A2A could create a moat for Google, making it difficult for other companies to compete in the AI landscape.
• The protocol's open-source nature and Apache licensing make it accessible and usable for everyone, without creating a moat for Google.
