Will be exploring this but so far using a Unity MCP has proven mostly enough to do pretty much anything from outside.
I guess the build pipeline part is nice as we can finally have a fully automated build process from build to distribution without finnicky build/postbuild scripts/profiles.
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.
