dsh-computer-use

When automating desktop computer tasks on macOS, users often grapple with issues like reliance on external services, privacy concerns, or complex setups. dsh-computer-use, a standalone plugin for DeepSeek Harness, offers a local solution that enables secure background control of applications and input devices without needing OpenAI components. Its core strength lies in an accessibility-tree-first design: a Swift daemon captures window states as numbered element trees, allowing AI models to act on indices with window-relative coordinates as a fallback; it also synthesizes mouse and keyboard input, delivering actions in the background to avoid disrupting the user's foreground. The plugin ships a complete toolkit, including service definitions, a local provider, approval policies, and an MCP server, catering to scenarios requiring privacy and efficiency. Ideal for AI developers, automation engineers, or macOS users, it provides an intuitive and powerful interface for computer use, easily integrable into intelligent assistants or testing workflows.
