About Uindow
Real browser automation for AI agents. Uindow ships a local MCP server that drives a real, signed Chromium/Electron browser with genuine OS-level input (real cursor movement, real keystrokes, native file dialogs) entirely on the user's own machine.

Overview
What is Uindow?
Uindow drives a real, signed Chromium/Electron browser with genuine OS-level input—actual cursor movement, real keystrokes, and native file dialogs—running entirely on your own machine and network. It provides an MCP server so AI agents can create and control web-automation agents that are immune to prompt injections.
How to use Uindow?
Launch the MCP server with npx -y @uindow/cli mcp and configure your MCP‑compatible client (Claude Desktop, Cursor, VS Code, etc.) to use that stdio command. Alternatively, use the integrated no‑code recorder or write automations in pure JavaScript inside the built‑in IDE.

- Automate CI/CD browser testing pipelines
- Write custom browser scripts using the integrated IDE
FAQ from Uindow
What makes Uindow immune to prompt injections?
It uses genuine OS‑level input (actual cursor movement, real keystrokes) rather than synthetic page events, so injected JavaScript in web pages cannot affect the automation.
How do I run the MCP server?
Run npx -y @uindow/cli mcp in your terminal. Then configure your MCP client (Claude Desktop, Cursor, VS Code, etc.) with the same command as shown in the README.
What are the system requirements?
Uindow runs on your own machine. The npx command fetches the signed Electron binary if not present, or you can use prebuilt binaries for macOS, Windows, and Linux from the Releases page. A free Uindow account
