Automation

Tempest Studio has a built-in MCP server, so an AI assistant such as Claude Code can open packages, read and edit objects, and take screenshots of the Studio while you watch.

Connect an assistant

The server runs while the Studio is open, on http://127.0.0.1:1423/mcp, reachable only from your own computer. Click the plug icon at the bottom of the activity bar: the dialog shows

• the claude mcp add command that registers the Studio with Claude Code;
• a .mcp.json snippet for other clients.

Both include an access token. It is made the first time the Studio runs and kept, so an assistant configured once keeps working. The port can be changed with the TEMPEST_STUDIO_MCP_PORT environment variable.

What an assistant can do

Tool	What it does
studio_windows, studio_state	List the windows; read what a window shows: the view, open package and object, edited files, the project and its save state, an open dialog or a pending question, tabs and the mod cooker's summary.
studio_open_workspace, studio_open_package	Open a game folder or a package.
studio_select, studio_set_mode, studio_open_table	Select an object, switch between Packages, Assembly and the mod cooker, open an assembly table.
studio_commands, studio_run_command	List every command of the Studio and run one, like a menu click: save, discard, undo, switch views, close a tab.
studio_confirm	Answer a confirmation (Discard, Replace a build…). Commands that ask stop and report the question instead of waiting.
studio_close_dialog	Close the dialog or palette that is open.
studio_project	Create, open, save or close a mod project.
studio_mod	The mod cooker: what the mod holds and what each delta changes, set the details and per-file choices, build and install. Publishing stays with you.
upk_call	Call any backend method: read objects, edit properties, export and replace assets.
studio_eval	Run code in the Studio's window, with every part of the Studio in reach.
studio_screenshot	Capture the window.
studio_new_window	Open a new window.

Edits made by an assistant are ordinary edits: they appear as unsaved (or are kept in your project), can be undone, and go into the mod like your own.

WARNING

The server gives full control over the Studio and the files it can reach. Only give the token to assistants you trust.
