What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

        r = subprocess.run([npx, "--yes", "@anthropic-ai/mcpb", *cmd])

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: CM_PROJECT (CarMaker project folder. All writes are confined to it.), CM_MODEL (Simulink model that cm_session_start opens (name on the MATLAB path, or a file).), CM_MATLAB_SESSION (Name under which MATLAB shares its engine.), CM_POPUP_TIMEOUT (Seconds after which CarMaker GUI pop-ups answer themselves with their default choice. Not set: they wait for a click.), CM_ENABLE (Optional tools, comma separated: tcl (raw Tcl in the GUI), experimental (Simulink structure edits).), CM_DISABLE (Tool groups to switch off, comma separated: standalone, study, matlab.). The author declared them in the registry entry; get the values from the project itself.
