How A2A and MCP Protocols Are Enabling AI Agent Collaboration
Interoperability between AI agents is becoming critical as enterprises adopt specialized AI workflows, with A2A and MCP emerging as key standards.
Presented by Google Cloud
AI agents are approaching a pivotal moment similar to the API revolution of the early 2010s, where REST and JSON simplified system integration. Today, Agent-to-Agent (A2A) and Model Context Protocol (MCP) are emerging as the foundational standards enabling seamless collaboration between AI agents, even when built on different models or platforms.
Why Interoperability Matters Now
Enterprises are increasingly deploying specialized AI agents for tasks like inventory management, logistics, and customer service. The real value lies in how these agents work together.
- A2A facilitates structured communication between agents, allowing them to advertise capabilities, discover peers, and execute workflows securely.
- MCP standardizes access to enterprise data and tools, enabling agents to operate with contextual awareness across systems.
Industry Adoption and Use Cases
Google Cloud initiated A2A as an open standard, with over 50 partners including Salesforce, Deloitte, and UiPath contributing to its development. Microsoft and SAP have integrated A2A into their AI platforms, while Zoom and Box are leveraging it for cross-agent interactions.
Real-world applications include:
- Customer service agents coordinating with inventory and logistics agents to resolve queries.
- Theme park operations agents adjusting staff allocation based on real-time sensor data.
Google Cloud’s Role
Google Cloud has released production-ready tools like the Python A2A SDK and Java Agent Development Kit. These integrate with BigQuery and other GCP services via MCP, simplifying agent development.
Why It Matters
Interoperability is becoming a competitive advantage. Enterprises that adopt A2A and MCP will build more scalable, agile AI systems, while those relying on isolated agents risk falling behind. As Tomas Talius, VP of Engineering at Google BigQuery, notes, this shift mirrors the rise of APIs—a foundation for modern cloud ecosystems.
