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.

            proc = subprocess.run(

    const result = spawnSync(candidate.command, [...candidate.args, "-c", "import sys; raise SystemExit(0 if sys.version_info >= (3, 10) else 1)"], {

        merged = dict(os.environ if env is None else env)

This one needs environment variables set before it will start: CITIES2_MODS_DIR (Optional path to the Cities: Skylines II Mods directory.), CITIES2_GAME_DIR (Optional path to the Cities: Skylines II install directory when auto-detection cannot find the game.), CITIES2_LOCALE_COK (Optional path to Locale.cok when the in-game encyclopedia file should be selected directly.). The author declared them in the registry entry; get the values from the project itself.
