Clearcote Browser MCP Server

What the code does

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 = spawnSync(cmd, args, { encoding: "utf8" });

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

        var container = File.Exists("/.dockerenv") || File.Exists("/run/.containerenv");

        r = subprocess.run([sys.executable, os.path.abspath(__file__)], capture_output=True, text=True,

            var psi = new ProcessStartInfo(file) { RedirectStandardOutput = true, RedirectStandardError = true, UseShellExecute = false, CreateNoWindow = true };

  return path.join(verDir, "_platform_specific", subdir, filename);

    venv = dict(os.environ)

import { existsSync, readFileSync, readdirSync, mkdirSync, writeFileSync, renameSync, rmSync, chmodSync } from "node:fs";

Optional settings from the registry entry, left out of the block above: CLEARCOTE_FINGERPRINT (Seed for one stable identity (the same seed is the same device on every run)), CLEARCOTE_PLATFORM (Platform persona), CLEARCOTE_PROXY (Proxy for all traffic, http://user:pass@host:port), CLEARCOTE_GEOIP (1: timezone, locale and WebRTC IP follow the proxy's exit IP), CLEARCOTE_CLOUD (1: the browser is a hosted Clearcote session (needs CLEARCOTE_API_KEY)), CLEARCOTE_API_KEY (API key for cloud mode and the run_task tool).
