Google Gives Its Agent-to-Agent Standard a Neutral Home

Google is handing control of one of the AI industry's emerging standards to a neutral body. Agent2Agent, the protocol it built to let AI agents describe themselves and pass work to one another, has become a hosted project of the Agentic AI Foundation, the group said this week.

A2A is a piece of plumbing. It defines "agent cards," small structured files in which an agent advertises what it can do and where to reach it, so that agents built on different frameworks can find each other, hand off tasks and coordinate without brittle one-off integrations. Google open-sourced the protocol in late 2025 and has now moved it out of its own orbit and into a foundation whose entire purpose is agent infrastructure.

The Agentic AI Foundation is young and growing quickly. It launched in December 2025 with fewer than 40 members and now counts more than 250, among them Google, Microsoft, Amazon, Anthropic, OpenAI, Bloomberg, Shopify and Block. It already hosts the Model Context Protocol, the other widely adopted standard for wiring models to tools and data. Putting A2A next to MCP under one roof is an attempt to give agent builders a stable, vendor-neutral base to work from.

Why give away a standard?

Handing a protocol to a foundation is a familiar move, and the logic is plain. A standard controlled by a single company is one that rivals hesitate to adopt, because it gives that company leverage over everyone downstream. Neutral governance lowers the resistance, and the payoff for the donor is influence over a technology that many others come to rely on. Kubernetes and a long list of open protocols took the same route for the same reason.

Whether it pays off is another matter. Standards succeed only when enough builders actually implement them, and the agent world is still crowded with competing conventions. Moving A2A to the foundation does not on its own make agents interoperable. It does remove one reason a wary competitor might have steered clear, and given who has already joined the foundation, that may be the point. The industry has agreed on where the standard should live. The harder agreement, on how agents should really talk to one another, is still being hammered out.
