Google Introduces A2A Protocol: A New Era of Agent Interoperability

Google announced the A2A (Agent-to-Agent) protocol, an open protocol that provides a standard way for agents to collaborate with each other, regardless of the underlying framework or vendor. This marks the beginning of a new era of agent interoperability.

A2A follows five key design principles:

• Embrace agentic capabilities: A2A focuses on enabling agents to collaborate in their natural, unstructured modalities, even when they don’t share memory, tools and context.
• Build on existing standards: The protocol is built on top of existing, popular standards including HTTP, SSE, JSON-RPC, making it easier to integrate with existing IT stacks.
• Secure by default: A2A is designed to support enterprise-grade authentication and authorization, with parity to OpenAPI’s authentication schemes at launch.
• Support for long-running tasks: A2A is designed to be flexible and support scenarios from quick tasks to deep research that may take hours or even days.
• Modality agnostic: The agentic world isn’t limited to just text, which is why A2A supports various modalities, including audio and video streaming.

Google is working with over 50 partners to advance this protocol, including Atlassian, Box, Cohere, LangChain, MongoDB, Salesforce, ServiceNow, and more.
