This is a very big signal of change on the AI map, where Microsoft has now decided to support Google’s Agent2Agent (A2A) protocol  just freshly minted to allow for intercommunication and mutual cooperation between AI under that name a very bold step forward in AI innovation, A2A being integrated into Microsoft’s Azure AI Foundry and Copilot Studio. 

Microsoft made the announcement on Wednesday, stating that it would join the A2A working group on GitHub and contribute to the protocol’s development. The collaboration of the two tech giants is destined to pave the way for an entirely different future of software: One in which AI agents are no longer limited to a single application or cloud, but will instead begin collaborating across platforms and ecosystems, contributing to adaptive and efficient workflows.

What is A2A?

Google Agent2Agent protocol, launched in April, allows AI-powered agents semi-autonomous programs to interact with each other across different services and clouds. This protocol enables agents to exchange goals and trigger actions, opening the door for more fluid and intelligent AI collaborations. Developers now have access to a set of interoperable components, ensuring these collaborations are both secure and efficient.

With A2A support coming to Azure AI Foundry and Copilot Studio, Microsoft’s AI agents will be able to collaborate with external agents, including those from other platforms like Google. For instance, a Microsoft AI agent could handle scheduling meetings while a Google AI agent drafts the corresponding email invitations.

AI Agents, The Future of Work

The ability to build complex, multi-agent workflows that span internal agents, partner tools, and production infrastructure is a game changer for businesses. Microsoft is aligning itself with the growing industry trend toward shared agent protocols, allowing for more flexible, scalable and governed workflows that maintain service-level agreements.

AI agent technology is rapidly gaining attention and investment as businesses look for ways to enhance productivity. A recent KPMG survey revealed that 65% of companies are already experimenting with AI agents, and Markets and Markets forecasts that the AI agent market will soar from $7.84 billion in 2025 to an impressive $52.62 billion by 2030.

Microsoft’s decision to embrace A2A follows its earlier support for MCP, Anthropic’s standard for connecting AI to data systems, in Copilot Studio. Google and OpenAI are also on board with MCP, marking another step in AI’s evolving role in the digital economy.

This collaboration between Microsoft and Google is more than just a technical advancement it’s a pivotal moment for the future of AI, where agents can work together to achieve more intelligent, adaptive, and efficient outcomes. The age of collaborative AI is here and Microsoft is leading the charge.
