Google’s A2A agent protocol moves into the Agentic AI Foundation
Focus: Earlier edition

Topics: Agent infrastructure, harness engineering, multi-agent systems, interoperability, context/tool standards
Evidence: Unspecified

Summary: Google’s Agent2Agent (A2A) protocol is moving into the Agentic AI Foundation, placing it alongside other open agent-infrastructure efforts under a more focused governance structure. A2A is designed for communication between independent AI agents, while MCP is primarily aimed at connecting AI applications to tools and data. The move is significant because it pushes agent-to-agent interoperability toward neutral, cross-vendor governance rather than provider-specific integrations.
Why it matters: As agent systems become more heterogeneous, interoperability is becoming part of the reliability stack. Standardized discovery, task exchange, long-running coordination, and cross-agent communication can reduce brittle custom glue code while creating clearer architectural boundaries between agents, tools, and context sources.
Original commentary: This is a strong update for material on harness engineering, context engineering, graph/agent architectures, tool use, and multi-agent workflows. A useful teaching distinction is emerging: MCP connects agents to tools and data; A2A connects agents to agents. That distinction can anchor diagrams, workshops, and application architecture examples.
