## Description

This MCP server provides full Chrome DevTools Protocol debugging capabilities for Node.js applications, built by ScriptedAlchemy with comprehensive breakpoint management, stepping controls, call stack inspection, and variable evaluation. The implementation features advanced debugging tools including conditional breakpoints, logpoints, exception handling, scope analysis with object property inspection, and frame restart capabilities, all accessible through a clean API that supports both text and JSON output formats. Built with TypeScript and chrome-remote-interface, it includes robust pause state management with unique pause IDs, console output capture, script source retrieval, and blackbox pattern support, making it ideal for AI-assisted debugging workflows, automated testing scenarios, and development tools that need programmatic access to Node.js runtime inspection without manual DevTools interaction.
