Google

AI research and products company — original developer of the A2A protocol and backer of the Agent Development Kit

Google initiated the A2A protocol, led its development in 2024, and then donated it to the Linux Foundation for neutral governance — keeping the protocol out of any single vendor’s hands, inviting broad participation, and aiming to make A2A a true industry standard rather than a Google-proprietary one. This is the canonical path for open-protocol evolution (cf. Kubernetes moving from Google-internal to CNCF stewardship).

Google

AI 研究与产品公司,Agent2Agent (A2A) 协议的原始开发者,Google DeepMind、Agent Development Kit (ADK) 的背后推动者。

在本 Wiki 中的角色

Google 是 A2A 协议的发起方。A2A 于 2024 年由 Google 主导开发,随后捐赠给 Linux Foundation 以中立化治理,确保生态多方参与。

主要贡献

  • A2A Protocol:开放的 agent 跨框架通信标准,处理 agent-to-agent 通信层
  • Agent Development Kit (ADK):Google 的 agent 开发工具包,与 A2A 配合使用(A2A 是协议层,ADK 是框架层)
  • Gemini:底层大语言模型,ADK 默认优化目标

在 Agent 技术栈中的布局

Google 在 agent 技术栈的多个层次都有布局:

层次Google 产品
模型层Gemini
框架层ADK(Agent Development Kit)
工具层MCP 生态兼容
通信层A2A Protocol

这是 Google 构建完整 agent 基础设施的战略布局,同时通过开放 A2A 标准吸引生态参与。
