The Agent2Agent protocol moves to the Linux Foundation
Google contributed the Agent2Agent protocol to a new Linux Foundation project, with AWS, Cisco, Microsoft, Salesforce, SAP and ServiceNow among the founding participants.
On June 23, 2025, the Linux Foundation launched the Agent2Agent project. Google contributed the A2A protocol, which it announced in April, so that no single vendor controls it.
What was announced
- Neutral governance. A2A now lives under the Linux Foundation instead of Google.
- Founding participants include AWS, Cisco, Google, Microsoft, Salesforce, SAP and ServiceNow.
- More than 100 companies have said they support the protocol.
Why it matters
Two months ago A2A was one vendor's draft. Now the large cloud and application vendors have a shared place to settle how agents talk to each other. That is good news for anyone who expects to run agents from more than one vendor, which is most companies.
A protocol for agents to talk to each other also raises the stakes on whether they mean the same thing when they do. If a sales agent hands a "qualified account" to a finance agent, and the two were built on different definitions, the handoff works and the answer is still wrong. Interoperability at the message level makes agreement on meaning more important, not less.
