What the code does

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.

        await fs.writeFile(fileOf(pid, aid) + '.tmp', JSON.stringify(doc));

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(cmd, args, { stdio: [input ? 'pipe' : 'ignore', 'pipe', 'pipe'] });

      await run('ffmpeg', ['-hide_banner', '-nostdin', '-y', '-i', tmp, '-af', 'aresample=44100:resampler=soxr:dither_method=triangular', '-ac', '2', '-c:a', 'pcm_s16le', path.join(dir, wav)]);
