Microsoft's Agent Framework blog confirms the MCP 2026-07-28 revision is in release candidate with a final lock on July 28, while A2A passed 150 adopting orgs with production SDKs in Python, JS, Java, Go, and .NET. The next two weeks are your window to review MCP breaking changes before the freeze. The MCP-for-tools plus A2A-for-agent-to-agent split is quietly becoming the assumed interop layer, so betting on it now is a reasonable call.
