Google A2A Released: Multi-Agent Collaboration Enters Protocol Competition
Google, together with multiple companies, released the Agent2Agent Protocol for collaboration between agents from different platforms and vendors.
After MCP solved the connection between agents and tools, A2A standardizes agent identity, task, and result exchange.
Agent Card, task lifecycle, messages, and artifacts form a common abstraction for cross-organizational collaboration.
The agent ecosystem is shifting from monolithic applications to a network of protocols, catalogs, identity, and governance.
Platform products should encapsulate capabilities as discoverable, authorizable, and auditable agent services.
Observe MCP/A2A division of labor, enterprise identity, cross-domain authorization, and practical interoperability cases.
