Microsoft Supports Google's A2A Protocol for AI Collaboration

Microsoft has announced support for Google’s open Agent2Agent (A2A) protocol, aiming to enable seamless collaboration and communication between AI agents across platforms, clouds, and organizations. The A2A protocol allows agents to securely exchange goals, manage state, invoke actions, and return results, fostering interoperability without vendor lock-in. Microsoft is integrating A2A into Azure AI Foundry and Copilot Studio, which will allow developers to build complex, multi-agent workflows that span internal and external tools. The company has also joined the A2A working group on GitHub, committing to contribute to the protocol’s ongoing development and tooling. This move aligns with a broader industry push towards open standards for AI agent interoperability and enhances the capabilities available to both developers and enterprises. Microsoft’s embrace of A2A is expected to accelerate the development and adoption of open, interoperable AI ecosystems.
