Description

This MCP server provides a backend that manages a pseudo-terminal running bash and a headless browser frontend using Playwright and Xterm.js to render terminal output and capture PNG screenshots. It supports both screenshot-based terminal state inspection without WebSocket connections and optional real-time terminal interaction via WebSocket. The system is designed for efficient asynchronous operation, containerization readiness, and robust error handling, making it ideal for LLM agents developing and debugging TUI applications.
