Peekaboo 🫣 - Mac automation that sees the screen and does the clicks.

Peekaboo brings high-fidelity screen capture, AI analysis, and complete GUI automation to macOS. Version 3 adds native agent flows and multi-screen automation across the CLI and MCP server.

What you get
- Pixel-accurate captures (windows, screens, menu bar) with optional Retina 2x scaling.
- Natural-language agent that chains Peekaboo tools (see, click, type, scroll, hotkey, menu, window, app, dock, space).
- Menu and menubar discovery with structured JSON; no clicks required.
- Multi-provider AI: GPT-5.1 family, Claude 4.x, Grok 4-fast (vision), Gemini 2.5, and local Ollama models.
- MCP server for Claude Desktop and Cursor plus a native CLI; the same tools in both.
- Configurable, testable workflows with reproducible sessions and strict typing.
- Requires macOS Screen Recording + Accessibility permissions (see docs/permissions.md).
