## Computer Use MCP that controls your entire desktop
Give AI assistants (Claude, Cursor, VS Code, etc.) the ability to control your desktop and automate tasks across any application.
**Claude Code (one-liner):**
```bash
claude mcp add terminator "npx -y terminator-mcp-agent@latest"
```
**Other clients (Cursor, VS Code, Windsurf, etc.):**
Add to your MCP config file:
```json
{
"mcpServers": {
"terminator-mcp-agent": {
"command": "npx",
"args": ["-y", "terminator-mcp-agent@latest"],
"env": {
"LOG_LEVEL": "info",
"RUST_BACKTRACE": "1"
}
}
}
}
```
See the [MCP Agent README](https://github.com/mediar-ai/terminator/tree/main/terminator-mcp-agent) for detailed setup instructions.
### Why Terminator MCP?
- **Uses your browser session** - no need to relogin, keeps all your cookies and auth
- **Doesn't take over your cursor or keyboard** - runs in the background without interrupting your work
- **Works across all dimensions** - pixels, DOM, and Accessibility tree for maximum reliability
### Use Cases
- Create a new instance on GCP, connect to it using CLI
- Check logs on Vercel to find most common errors
- Test my app new features based on recent commits
## What's new
- 01/09/26 - Mediar IDE (Cursor for Windows automation) is in public access - [download now](https://cdn.crabnebula.app/download/mediar/mediar/latest/platform/windows-x86_64)
- 10/30 Public alpha is live - [Cursor for Windows automation](https://www.mediar.ai)
- 09/26 Terminator was on [Cohere Labs podcast](https://www.youtube.com/watch?v=cfQxlk8KNmY), also [check the slides](https://092025-cohere.mediar.ai/)
- 08/25 Big release — NodeJS SDK in YAML workflows, run JS in browser, OS event recording → YAML generation in MCP, and more
- 08/25 [we raised $2.8m to give AI hands to every desktop](https://x.com/louis030195/status/1948745185178914929)
## Why Terminator
### For Developers
- Create automations that work across any desktop app or browser
- Runs 100x faster than ChatGPT Agents, Claude, Perplexity Comet, BrowserBase, BrowserUse (deterministic, CPU speed, with AI recovery)
- >95% success rate unlike most computer use overhyped products
- MIT-licensed — fork it, ship it, no lock-in
We achieve this by pre-training workflows as deterministic code, and calling AI only when recovery is needed.
### For Teams
[Our public beta workflow builder](https://www.mediar.ai) + managed hosting:
- Record, map your processes, and implement the workflow without technical skills
- Deploy AI to execute them at >95% success rate without managing hundreds of Windows VMs
- Kill repetitive work without legacy RPA complexity, implementation and maintenance cost

- **No**: Not available on this platform.
## How to Inspect Accessibility Elements (like `name:Seven`)
To create reliable selectors (e.g. `name:Seven`, `role:Button`, `window:Calculator`), you need to inspect the Windows Accessibility Tree:
### Windows
- **Tool:** [Accessibility Insights for Windows](https://accessibilityinsights.io/downloads/)
- **Alt:** [Inspect.exe](https://learn.microsoft.com/en-us/windows/win32/winauto/inspect-objects) (comes with Windows SDK)
- **Usage:** Open the app you want to inspect → launch Accessibility Insights → hover or use keyboard navigation to explore the UI tree (Name, Role, ControlType, AutomationId).
> These tools show you the `Name`, `Role`, `ControlType`, and other metadata used in Terminator selectors.
### Platform Support
| Platform | CLI | MCP Agent | Automation | Installation Method |
|----------|:---:|:---------:|:----------:|---------------------|
| Windows | Yes | Yes | Yes | npm/bunx |
**Note:** Terminator currently supports Windows only. macOS and Linux support is not available.
