Linux Foundation Launches Agent2Agent Project to Standardize AI Agent Interoperability
A2A was originally developed by Google and has now been donated to the Linux Foundation.
The Linux Foundation has officially launched the Agent2Agent (A2A) project, a significant open-source initiative aimed at standardising communication between AI agents across platforms.
Announced at the Open Source Summit North America, A2A was originally developed by Google and has now been donated to the Linux Foundation to ensure vendor-neutral governance and encourage widespread adoption.
A2A enables AI agents to securely discover, communicate, and collaborate with each other—regardless of the platform, framework, or vendor they’re built on. Since its unveiling in April, the protocol has gained support from more than 100 companies, including AWS, Cisco, Microsoft, Salesforce, SAP, and ServiceNow.
"The Agent2Agent protocol establishes a vital open standard for communication, enabling the industry to build truly interoperable AI agents across diverse 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," Rao Surapaneni, Vice President and GM of Business Applications Platform, Google Cloud, said.
The A2A project includes SDKs and tools to help developers build interoperable agents, reducing vendor lock-in and enabling scalable AI ecosystems. Google Cloud VP Rao Surapaneni stressed the importance of A2A as a foundational communication layer for AI agents.
The Linux Foundation will now lead A2A development with a focus on extensibility, identity, security, and real-world use cases. The protocol is publicly available on GitHub, and organizations are invited to contribute to its growth.
“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,” Jim Zemlin, executive director of the Linux Foundation, said.
Under the Linux Foundation’s governance, the A2A protocol will maintain a vendor-neutral approach, encourage broad and inclusive community contributions, and continue to prioritize extensibility, robust security, and practical usability across diverse industries.
Last month, Microsoft embraced open AI agent collaboration with the upcoming integration of the Agent2Agent (A2A) protocol into its Azure AI Foundry and Copilot Studio.
The move aims to support seamless interoperability between AI agents across platforms, clouds, and organisations.
