What the code does

We read the source, 22 h ago · rules 995398eba69f

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

        await fs.writeFile(out, bytes);

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

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 r = await redis.eval(

                return JSON.parse(await readFile(path.join(base, rel), 'utf8'));

    const child = spawn(command[0], command.slice(1), { stdio: 'inherit', shell: false });

    const drop = STANDING_HIP_HEIGHT * (root.height - 1) + root.rise;

            if (reset) { state.cursor = null; state.total = 0; grid.innerHTML = skeletons(); stateEl.hidden = true; }

Put your own value in place of <THREE_WS_API_KEY> (Your three.ws bearer credential: an API key (sk_live_… / sk_test_…) or OAuth access token. Every copy-trade subscription, intent, and fee is scoped to the account it identifies. Required for all tools except a leader's public aggregate earnings. Mint one at https://three.ws/dashboard/developers. Treat like cash). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: THREE_WS_BASE (Base URL of the three.ws API that serves the copy-trading endpoints. Override only when self-hosting or targeting a preview deployment), THREE_WS_TIMEOUT_MS (Per-request timeout in milliseconds for the live copy-trading reads and writes).
