Teach your agent any app.

Computer use, without the screenshots. Sabir learns what every Windows app can do and hands it to Claude, Codex, Gemini CLI or any MCP agent as real tools — fast, exact, and with your permission.

learned once, reused by every agent you connect

Measured on a Windows 10 PC. This is Sabir’s execution time — your agent still makes its own model calls to decide what to do.
Why not just computer use?

Stop guessing pixels.

Computer use takes a screenshot, looks at it, guesses where the button is, moves the mouse and clicks — then takes another screenshot. For every single click. Sabir skips all of that.

How it works

Learn. Ask. Act.

Permission request: Claude wants to use Photoshop
01 · Ask

Your agent asks first

The first time an agent wants an app, Sabir asks you: Always allow, Allow once, or Deny.

02 · Learn

Sabir learns the app

It reads the app through Windows UI Automation and saves every button, menu, field and switch as a reusable tool.

Sabir activity log
03 · Act

Your agent gets real tools

Tools like notepad__file_save or calculator__equals appear in your agent over MCP. Every action is logged.

What you get

Everything an agent needs to use your PC.

Zero screenshots

No image tokens, no visual guessing. Sabir talks to the app’s interface directly.

No guessing

Every click hits the exact control by its automation ID — not a pixel that might have moved.

Your mouse stays yours

Sabir works in the background. Keep typing while your agent works in another app.

Learned once, every agent

One MCP server. What Sabir learned for Claude is ready for Codex and Gemini CLI too.

You stay in control

Per-app permissions, a pause button in the tray, and a full activity log on your PC.

Any app with a UI

Notepad, Calculator, Explorer, Office, internal tools — if Windows can see it, your agent can use it.

The setup writes the MCP config for you. Restart your agent once — done.

FAQ

Questions

Windows says “Windows protected your PC”. Is that normal?

Yes. Sabir is new and not code-signed yet, so SmartScreen shows a warning. Click “More info” → “Run anyway”. The full source code is on GitHub.

Which apps work?

Any app that exposes Windows UI Automation — that includes most classic Windows apps, UWP apps like Calculator, Office and many Electron apps. Apps that draw everything themselves (some games, custom canvases) expose little or nothing.

Does my agent still need to think?

Yes. Sabir makes each action fast and exact; your agent still decides what to do. The 84 ms above is Sabir’s execution time, not the agent’s total time.

Is it safe?

The MCP server only listens on your own PC (127.0.0.1) and needs a secret token. Every agent has to ask you per app, you can pause everything from the tray, and every action is written to a local log.

What does it cost?

Nothing. Sabir is free and open source under the MIT license.
