Stealth browser automation that actually works. Runs Camoufox (custom Firefox) in Docker with zero Chrome DevTools Protocol exposure, real OS-level mouse and keyboard input via PyAutoGUI, and a JSON HTTP API + MCP server to control it all remotely. Watch it live via noVNC. Run a single instance or spin up a cluster behind HAProxy with Redis cookie sync, request queuing, and sticky sessions. Drive it with curl, pipe YAML scripts through stdin, send multi-step scripts via the API, use page loaders to auto-handle popups and paywalls, or connect AI agents directly via MCP. Optional Bearer token auth via AUTH_TOKEN.

The image avoids Chromium CDP signals and keeps its generated Linux font and WebGL surfaces internally consistent. Detection results still depend on the site, network exit, timezone, browser build, and test date.

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.
