palette-computer-use

Palette Computer Use gives Palette Code agents a screen, mouse and keyboard on the desktop: a local CLI and a stdio MCP server that read the accessibility tree, take screenshots and drive apps on macOS, Linux and Windows.

It is a Palette-branded build of the open-source open-computer-use project by iFurySt, redistributed under the MIT License. See NOTICE.md for what changed and THIRD_PARTY_NOTICES.md for bundled third-party components.

Platforms and notes

• Bundled runtimes: darwin-arm64, darwin-x64 (universal Palette Computer Use.app), linux-arm64, linux-x64, win32-arm64, win32-x64.
• macOS 14 or newer. Grant Accessibility and Screen Recording to "Palette Computer Use" (bundle id xyz.pltt.palette.computeruse) when pcu doctor asks.
• The macOS app in this build is ad-hoc signed; macOS may ask for permissions again after an update because TCC ties grants to the signature.
• Linux needs a signed-in desktop session with AT-SPI2 / D-Bus accessibility; Windows needs a signed-in desktop session for UI Automation.
• Node.js 18 or newer is required for the launcher.
