AI-controlled browser farm: N isolated Chromium instances with 36 MCP tools
AI-controlled browser farm: N isolated Chromium instances with 36 MCP tools. Exposed over MCP by the gdd mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Simulate multiple real users across 22 device types — test your site like it's launch day.
Everything the assistant can do here goes through one of these:
Navigation — The Navigation tool exposed by this serverInteraction — The Interaction tool exposed by this serverEmulation — The Emulation tool exposed by this serverEditions — GDD ships as three apps over one shared core. The two GUIs differ only in the desktop toolkit (WebView2 on Windows, Avalonia on Linux/macOS); allInstallation goes through your MCP client rather than a global install: point it at ghcr.io/cap-of-tea/gdd on a container image and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the browser automation options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. GDD's toolset — Navigation, Interaction, Emulation and 1 more — is a fair guide to whether it matches your workflow. It is maintained by imVSmirnov; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against GDD's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
| Tool | What it does |
|---|---|
| Navigation | The Navigation tool exposed by this server. |
| Interaction | The Interaction tool exposed by this server. |
| Emulation | The Emulation tool exposed by this server. |
| Editions | GDD ships as three apps over one shared core. The two GUIs differ only in the desktop toolkit (WebView2 on Windows, Avalonia on Linux/macOS); all three expose the same 39 MCP tools. |
