What the code does
We read the source, 4 h ago · rules 995398eba69f
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.
subprocess.run(['sips', '-s', 'format', 'ppm', path, '--out', tmp],
with open(os.path.join(out, fname), 'w', encoding='utf-8') as f:
const r = spawnSync(PY, ['-c', 'import sys; sys.exit(0 if sys.version_info >= (3, 9) else 1)']);

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
