Osascript MCP Server

Let Claude control your Mac. Move windows, click menus, type text, read clipboard, manage browser tabs, take screenshots, run Shortcuts - 18 typed tools with input validation and security guardrails. It runs locally over stdio via the published package.

People who work with app and clipboard and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
