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.
path = os.path.join(repo, profile.PROFILE_PATH)
proc = subprocess.run(
function el(html){ var d=document.createElement('div'); d.innerHTML=html.trim(); return d.firstChild; }

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.
