What the code does
We read the source, 5 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.
const child = spawn(executable, ['--cli', ...args], { shell: false, windowsHide: true, stdio: ['ignore', 'pipe', 'pipe'], env: childEnv });
if (entry.isDirectory()) pending.push(path.join(entry.parentPath, entry.name));
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
