Google Cloud announced the transfer of its groundbreaking Agent2Agent (A2A) protocol to the Linux Foundation at Open Source Summit North America, establishing a new collaborative project aimed at fostering interoperable AI agent ecosystems.
The donation creates an independent, vendor-neutral entity supported by major technology companies including Amazon Web Services, Cisco, Microsoft, Salesforce, SAP, and ServiceNow.
The newly formed Agent2Agent project represents a significant milestone in AI development, bringing together industry leaders under the Linux Foundation’s trusted governance framework.
More than 100 companies now support the A2A protocol, with AWS and Cisco joining as the newest validators of this open standard for AI agent communication.
“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 addresses critical challenges in scaling AI agents across enterprise environments by enabling seamless interoperability regardless of platform, vendor, or framework.
This collaborative approach aims to break down existing silos that currently limit artificial intelligence potential across organizational boundaries.
Google Cloud Donates A2A Protocol
The A2A protocol establishes a common language for AI agents to discover capabilities, securely exchange information, and coordinate complex tasks across diverse systems.
Originally launched by Google in April 2025, the protocol has evolved to support dynamic, multi-agent environments where autonomous systems can operate collaboratively.
“The Agent2Agent protocol establishes a vital open standard for communication, enabling the industry to build truly interoperable AI agents across diverse platforms and systems,” explained Rao Surapaneni, Vice President and GM of Business Applications Platform at Google Cloud.
Key technical capabilities include secure agent discovery mechanisms, standardized information exchange protocols, and coordinated task execution frameworks.
The protocol’s architecture emphasizes extensibility, security, and real-world usability across industries, allowing developers to build modular solutions that reduce vendor lock-in while accelerating innovation.
Accelerating Adoption
Founding members bring substantial resources and expertise to advance the protocol’s development and adoption.
AWS plans to contribute project enhancements and provide access to comprehensive agentic frameworks and services.
The project establishes four key objectives: driving A2A specification adoption as the premier industry standard, fostering a diverse global developer community, ensuring neutral governance under Linux Foundation oversight, and accelerating secure innovation in collaborative AI applications.
Cisco is integrating A2A support directly into key AGNTCY open source components, including Directory, Identity, SLIM Messaging, and Observability frameworks.
Microsoft emphasizes combining open interoperability with enterprise-grade capabilities for responsible, scalable agent deployment.
Salesforce views the initiative as extending their open platform to empower Agentforce orchestration across disconnected systems, while SAP focuses on enabling seamless automation across traditionally siloed enterprise applications.
ServiceNow highlights its unique positioning with AI Agent Control Tower capabilities and enterprise-grade AI Platform for business transformation.
“This is a critical step forward—not just for our customers, but for the entire ecosystem—as we enable intelligent agents that are open, secure, and scalable,” stated Joe Davis, EVP of Platform Engineering & AI Technology Group.
Organizations interested in contributing can access the project through the Agent2Agent GitHub repository.
