Version control
Review and commit source-backed design changes with Git.
Canvas edits autosave as .fnx source in a project folder, so git diff shows the change when the project is in a repository. In non-Store builds, File → Review Changes opens a review UI and File → Commit… records the reviewed change. A new project is initialized when a bundled or system Git is available, unless the folder is already inside a repository.
The external MCP server has no vcs_begin_task, vcs_commit, or vcs_promote tools. An agent can edit through MCP and use ordinary Git tools against the project folder if its environment allows. Screenshot the result and review the source diff before committing.
The non-Store app bundle includes Git, so Xcode Command Line Tools are not normally required. Mac App Store feature builds save projects without automatic git init; use a separate Git client for version history there.
