Peekaboo 2.0 – Free the CLI from its MCP shackles

Read Original

The article introduces Peekaboo 2.0, a tool for capturing macOS screenshots for AI agents. Originally an MCP server, it's now refactored into a core Swift CLI to free agents from MCP overhead, allowing on-demand use and saving context space. It details installation via Homebrew, configuration for OpenAI GPT-4 Vision analysis, and examples of using it to debug UIs or analyze webpages via command line.
