What the code does
We read the source, 20 min ago · rules 3dff92dd89df
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.
return path.join(ROOT, udid);
let p = Process()
const child = spawn(BINARY, args, { detached: true, stdio: ['ignore', log, log] });

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.
