We Built an Open Protocol So AI Agents Can Actually See Your Screen

You know what's wild? Every major AI lab is building "computer use" agents right now. Models that can look at your screen, understand what they see, and click buttons on your behalf. Anthropic has Claude Computer Use. OpenAI shipped CUA. Microsoft built UFO2. And every single one of them is independently solving the same problem: how do you describe a UI to an AI? We thought that was broken, so we built Computer Use Protocol (CUP) , an open specification that gives AI agents a universal way to perceive and interact with any desktop UI. One format. Every platform. MIT licensed.
