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.

        out = subprocess.check_output([node, "-p", "process.versions.node"], text=True).strip()

    const jobDir = path.join(dir, job.id);

    env = dict(os.environ)
