Apparently this is the same surface as Unity MCP.

> The same surface is open to any agent, whether that's Unity's own tooling routing through its MCP server, a third-party assistant, or a script you write yourself. Unity’s AI is one consumer of it, not a replacement for it.

I hope this means games get more automated tests! The state of the industry is generally woeful in that regard.

Ok, I spent some time with it and I think the biggest updates are:

- Easier automating builds via shell

- Creating entry points for agents to modify and probe a running built game when in dev mode. This is huge, as you can create a lot of scaffolding to debug really complex states and stuff.

For most of the dev stuff, I'd still go for the usual UnityMCP.
