Google’s Agent2Agent (A2A) Protocol: Revolutionizing AI Collaboration

Google’s Agent2Agent (A2A) protocol, unveiled at Cloud Next 2025, is poised to reshape software development by enabling seamless AI agent interaction.

What is A2A and Why Interoperability Matters?

A2A establishes an open standard allowing AI agents from diverse vendors to securely communicate and collaborate using JSON-based “Agent Cards”. This breaks down silos, facilitating complex multi-agent workflows like automated supply chain planning.

It complements protocols like MCP by focusing specifically on direct agent-to-agent communication, fostering a truly interoperable AI ecosystem.

Key Benefits of A2A

A2A enhances productivity and lowers development costs by standardizing agent integration. Faster innovation is spurred as developers easily combine best-of-breed agents.

Supported by Google’s Agent Development Kit (ADK) and key enterprise partners, A2A delivers practical automation and future-proofs AI investments through improved digital workflows.
