Peekaboo (macOS Screen Capture)

Peekaboo MCP Server provides macOS screen capture and window management capabilities to AI assistants through a Node.js interface. Developed by Peter Steinberger, it combines a Swift CLI for native macOS functionality with a TypeScript MCP server that exposes tools for capturing screenshots, analyzing images with AI providers (Ollama, OpenAI), and listing running applications and windows. The implementation features intelligent application matching, window targeting by title or index, and support for various capture modes (screen, window, multi-window), making it particularly valuable for AI assistants that need to understand and interact with visual content on macOS systems.
