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.

  const r = spawnSync(finder, [cmd], { stdio: ["ignore", "ignore", "ignore"] });

    return os.path.join(root, name)

        self._proc = subprocess.Popen(args, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
