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.

        run = subprocess.run([codex, "queue", "--thread", door["thread"], "--message", text], env=env,

    workers = Workers(dict(os.environ))
