Microsoft has recently committed to supporting Google’s newly introduced open protocol, known as Agent2Agent (A2A), aimed at facilitating communication between AI agents. This announcement was made on Wednesday, marking a significant step in the evolution of AI technologies.
The integration of A2A will be incorporated into Microsoft’s Azure AI Foundry and Copilot Studio, with the company also joining the A2A working group on GitHub to contribute to the ongoing development of the protocol and associated tools. In a blog post, Microsoft highlighted that this move is foundational for the next wave of software development, characterised by collaborative, observable, and adaptable systems. They emphasised that the most effective AI agents will not be confined to individual apps or clouds, but will operate seamlessly across different work environments, domains, and ecosystems.
The A2A framework, unveiled by Google in early April, allows semi-autonomous AI programs to collaborate across various platforms, clouds, and services. By utilising A2A, these agents can share objectives and initiate actions while ensuring secure collaboration through a suite of interoperable components. Once A2A is implemented in Azure AI Foundry and Copilot Studio, Microsoft agents will have the capability to engage with external agents built on alternative platforms. An example of this functionality might include a Microsoft agent coordinating a meeting while a Google agent prepares the email invitations.
Microsoft underscored that this initiative enables customers to create sophisticated, multi-agent workflows that integrate internal agents, partner tools, and existing infrastructure, all while upholding governance and service-level agreements. The company is aligning its efforts with a broader industry trend that advocates for shared agent protocols.
Despite its current limitations, agent technology is garnering increasing attention and investment as businesses seek to leverage it for enhanced productivity. A recent survey by KPMG revealed that 65% of companies are experimenting with AI agents, while a report by Markets and Markets anticipates that the AI agent market will swell from $7.84 billion in 2025 to $52.62 billion by 2030.
Microsoft’s endorsement of the A2A protocol follows its earlier integration of the MCP standard, introduced by Anthropic, which facilitates AI connectivity to data-laden systems in Copilot Studio. Other prominent AI model developers, including Google and OpenAI, have also expressed intent to adopt MCP, showcasing a collaborative spirit in advancing AI interconnectivity.
