What the code does
We read the source, 2 d 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.
out = subprocess.run([exe, "--version"], capture_output=True, text=True, timeout=30,
child = spawn(KEELYARD, ["hook", "opencode", event], { stdio: ["pipe", "pipe", "ignore"], windowsHide: true });
chk = subprocess.run(task["check"], shell=True, cwd=repo, capture_output=True, text=True, encoding="utf-8", errors="replace", timeout=600)

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.
