The Linux Foundation announced the launch of the Agent2Agent (A2A) project on Monday at the Open Source Summit North America. It is a major step toward building open standards for interoperable AI agents. Originally developed by Google, the A2A protocol is now being donated to The Linux Foundation to ensure vendor-neutral governance and broader industry collaboration.
The A2A protocol enables AI agents to securely discover, communicate, and collaborate across different platforms, frameworks, and vendors. Google introduced the technology in April. A2A has since gained backing from over 100 organisations, including AWS, Cisco, Microsoft, Salesforce, SAP, and ServiceNow.
The protocol addresses the growing need for agents to work together across dynamic environments and infrastructure.
“We are happy to be the new home of the Agent2Agent Protocol project,” said Jim Zemlin, executive director of The Linux Foundation.
“By joining the Linux Foundation, A2A is ensuring the long-term neutrality, collaboration and governance that will unlock the next era of agent-to-agent powered productivity.”
The protocol comes with a full set of SDKs and tooling to help developers build cross-compatible agents and avoid vendor lock-in.
Rao Surapaneni, vice president and GM of business applications platform at Google Cloud, emphasised that the Agent2Agent protocol is crucial for establishing an open communication standard. This standard allows the industry to develop AI agents that can truly work together across various platforms and systems.
“By collaborating with the Linux Foundation and leading technology providers, we will enable more innovative and valuable AI capabilities under a trusted, open-governance framework.” stated Surapaneni.
The A2A project, hosted under the Linux Foundation, will focus on extensibility, security, and real-world usability. The long-term vision includes developing complementary standards for agent identity, delegation, security, and reputation.
By contributing A2A to an open ecosystem, Google and its partners hope to accelerate enterprise adoption of intelligent agentic systems. Developers and organisations can participate via the A2A GitHub page.
