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.

cue.innerHTML = p < 0.04 ? '<i>↓</i> scroll to see what happened' : p < 0.9 ? '<i>↓</i> keep scrolling' : '<i>↓</i> next: try it yourself';

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.
