TLDR: The Linux Foundation has announced its adoption of the Agent2Agent (A2A) protocol, an open standard initiated by Google, aimed at enabling secure and interoperable communication between diverse AI agents. This move, supported by over 100 technology companies including AWS, Microsoft, and Salesforce, is set to address fragmentation in enterprise AI and foster a new era of collaborative AI systems.
DENVER, CO – In a significant stride towards a more integrated artificial intelligence ecosystem, the Linux Foundation announced at the Open Source Summit in Denver its decision to host the Agent2Agent (A2A) protocol. This open standard, originally developed by Google, is poised to revolutionize how AI agents interact, ensuring secure and interoperable communication across disparate platforms, vendors, and frameworks.
The adoption of A2A by the Linux Foundation marks a pivotal moment in addressing one of AI’s most pressing challenges: the current fragmentation that limits the deployment and scalability of enterprise AI. Historically, AI implementations have often resulted in isolated systems, hindering the ability of autonomous agents – software entities capable of independent action and decision-making – to discover each other, exchange information, and collaborate effectively.
The A2A protocol is designed to overcome these hurdles. It functions as a crucial communication layer, allowing AI agents to understand each other’s capabilities, securely share data, and coordinate complex tasks regardless of their underlying technology stack. Technically, A2A leverages JSON-RPC 2.0 over HTTP for standardized communication, with server-sent events facilitating real-time streaming interactions. A key feature is the use of ‘AgentCards,’ which act as digital business cards containing capability descriptions and connection information, enabling seamless agent discovery.
Initially conceived by Google, the A2A protocol has rapidly gained widespread industry support, now backed by more than 100 leading technology companies. This formidable coalition includes industry giants such as Amazon Web Services (AWS), Cisco, Microsoft, Salesforce, SAP, and ServiceNow, many of whom plan to integrate A2A into their own AI infrastructure and tooling. Microsoft, for instance, has already integrated A2A support into Azure AI Foundry and enabled A2A agent invocation through Copilot Studio, allowing enterprises to participate in multi-vendor agent workflows without replacing existing investments.
Jim Zemlin, Executive Director of the Linux Foundation, emphasized the strategic importance of this move in his keynote speech. “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,” Zemlin stated. This governance model is critical for fostering vendor neutrality and ensuring the protocol evolves through community input rather than single-vendor control, addressing enterprise concerns about proprietary lock-in.
Rao Surapaneni, Vice President and GM of Business Applications Platform at Google Cloud, echoed this sentiment, stating, “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.”

The impact of A2A is expected to be profound. It is anticipated to become a cornerstone for building truly interoperable, multi-agent AI systems, accelerating innovation and improving modularity. The move aligns with industry predictions, such as Gartner’s forecast that a third of all applications and enterprises will be powered by Agentic AI by 2028. While other agent-to-agent protocols like Anthropic’s Model Context Protocol (MCP) and the Agent Communication Protocol (ACP) also exist, A2A’s broad industry backing and open governance under the Linux Foundation position it as a leading contender in the race to standardize AI communication.
