What is the GDD MCP Server?

AI-controlled browser farm: N isolated Chromium instances with 36 MCP tools

What it actually does

Simulate multiple real users across 22 device types — test your site like it's launch day.

  • Multi-device — — Run N isolated Chromium instances with 22 device presets (phones, tablets, desktops)
  • AI-native — — 39 MCP tools for Claude Code, Cursor, or any MCP-compatible client
  • Cross-platform — — Native GUI with a live video wall on Windows, Linux & macOS, plus a headless server for CI/CD
  • Full interaction — — Navigate, tap, type, press keys and shortcuts, drag, swipe, scroll, hover, handle dialogs, take screenshots
  • Human-like input — — humanize=true drives a continuous cursor path (cubic Bézier with easing and micro-jitter) that carries over between clicks, hovers and drags; taps fire a single device-appropriate input (touch or mouse), never both
  • Proxy support — — Route every browser through an upstream proxy with GDD_PROXY (with optional auth)
