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 child = spawn(python, [STAGE_SCRIPT], {

    try { privateWrite(path.join(root, filename), record); return true; }

        completed = subprocess.run(

      : type === 'knowledge-update' ? UPDATE
        : type === 'single-session-preference' ? PREFERENCE : BASE + FIELDS;

    const userconfig = join(app, '.npmrc');
