A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

        proc = subprocess.run(cmd, capture_output=True, text=True, timeout=120, env=env)

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.

        cand = os.path.join(d, want)

    subprocess.run([CLI, "sch", "export", "netlist", "--format", "kicadxml", "--output",

    exec(block, ns)  # noqa: S102 (plain dict literals)

    env = dict(os.environ)
