What open-computer-use is

Open Computer Use is a local MCP server for AI agents to inspect and operate desktop apps through accessibility interfaces. Its nine core tools cover finding apps, capturing accessibility trees and screenshots, clicking, scrolling, dragging, typing, pressing keys, performing secondary actions, and setting control values. The project documents setup for Codex CLI and App, Claude Code, Gemini CLI, and opencode, with manual configuration for other MCP clients. It also includes a ZCode plugin that installs the skill and connects an MCP server. The project says it runs on the user's machine and uses accessibility interfaces for core app actions without taking over the real mouse and keyboard. Password managers are refused; app launching, focus changes, and global input injection require explicit environment-variable gates. It supports macOS, Windows, and Linux. macOS 14 or later requires Accessibility and Screen Recording permissions; Linux requires AT-SPI2. Additional window-level tools are currently available on Windows, with macOS and Linux support in progress. The software is free, MIT-licensed, and intended for authorized machines.
