# SwiftCUA: reconstructing a macOS computer-use service

> SwiftCUA reconstructs the behavior of a macOS computer-use service in Swift 6 after studying the Codex Computer Use.app bundle, its local IPC, permissions and input engine. It provides a background service, CLI, JavaScript bridge and MCP servers for accessibility inspection, screenshots and input, with separate research reports on the original.

## Requirements & limits

- **Prerequisites:** macOS with Screen Recording and Accessibility permission is required for the installed service.
- **Prerequisites:** Swift 6 is used for the service; the JavaScript client requires Node.js 18 or newer.
- **Limits:** The reconstructed service does not support locked-screen operation or byte-compatible communication with the original service.
- **License:** MIT License.
