Redmond, Thursday, 8 May 2025.
Microsoft integrates Google’s Agent2Agent protocol with its AI platforms, enhancing cross-platform agent communication, a move reflecting broader trends towards open AI interoperability and collaborative software development.

Strategic Protocol Adoption

Microsoft’s decision to adopt Google’s Agent2Agent (A2A) protocol marks a significant shift in the AI landscape, announced on May 7, 2025 [1]. The integration will be implemented across two major platforms: Azure AI Foundry and Copilot Studio, which currently serves over 230,000 organizations, including 90% of Fortune 500 companies [4]. This strategic move follows Microsoft’s earlier embrace of Anthropic’s Model Context Protocol (MCP) in April 2025 [5], demonstrating the company’s commitment to fostering open standards in AI communication.

Technical Implementation and Market Impact

The integration leverages JSON-RPC over HTTP for cross-cloud AI collaboration, enabling agents to exchange context while maintaining robust security protocols [3]. Market analysis suggests substantial growth potential, with the AI agent segment projected to expand from $7.84 billion in 2025 to $52.62 billion by 2030, while current data shows 65% of companies are already experimenting with AI agents [1]. Microsoft’s Azure AI Foundry platform, currently utilized by over 70,000 enterprises [4], will incorporate A2A protocol to facilitate seamless agent interactions across different clouds, applications, and services.

Enterprise Integration and Security Framework

Microsoft is implementing enterprise-grade safeguards through Microsoft Entra and Azure AI Content Safety [4]. The technical architecture includes sophisticated credential management and security controls through Azure API Management, ensuring protected backend resource access [6]. This infrastructure allows for complex, multi-agent workflows while maintaining governance and service level agreements across organizational boundaries [4]. The integration demonstrates Microsoft’s commitment to responsible AI development, with transparency notes and governance solutions integrated into their operational framework [2].

Future Implications and Industry Collaboration

As part of this initiative, Microsoft has joined the A2A working group on GitHub [1], signaling a collaborative approach to protocol development. The integration represents a broader industry trend toward interoperability, with over 50 major technology partners, including Atlassian, Box, and Salesforce, participating in the A2A ecosystem [7]. While the exact timeline for full implementation remains [alert! ‘specific deployment dates not confirmed’], Microsoft has already released sample implementations in Semantic Kernel demonstrating A2A integration with both .NET and Python frameworks [4].
