Summary
Agent2Agent Protocol, the standard Google originally created so AI agents can talk to each other, will become part of the Agentic AI Foundation. A2A is positioned as a complement to Model Context Protocol, known as MCP. MCP connects AI applications with tools and data, while A2A aims to standardize communication between independent agents. The move strengthens an open architecture in which agents built by different vendors can work together without proprietary integrations for every combination.
Why it matters
Interoperability could become one of the most strategic layers of the agent market. If MCP and A2A win broad adoption, companies can reduce dependence on a single vendor and build systems where models, tools and agents can be swapped with less friction.
Practical implications
- New agent systems should clearly separate model, tools and orchestration to make vendor changes easier.
- Technical teams should evaluate A2A alongside MCP before building proprietary protocols for agent-to-agent communication.
- Agencies can design automations with interchangeable components instead of depending on a single closed ecosystem.
