Hey, thanks for the feature request.
This is partially available already. In the IDE, Agent has a browser tool, so it can control the built-in browser navigation, screenshots, clicks, and self-verify tasks on the web. More details here: Browser | Cursor Docs
Full local computer use controlling your whole desktop and any apps on your machine like Codex CUA or Claude Code desktop is not available natively yet. As a workaround, you can connect a computer-use MCP server. Via MCP, Agent can get access to those capabilities: Model Context Protocol (MCP) | Cursor Docs
I’ve logged the request for a native local computer-use mode. There’s no ETA yet. If you want, you can follow a related thread where this idea is already being discussed: Feature Request: Computer Control / Coworker Mode for Cursor
