Node.js Debugger

This Node.js debugger MCP server by qckfx provides programmatic debugging capabilities for AI agents through the Chrome DevTools Protocol, enabling full process lifecycle management and interactive debugging sessions. The implementation spawns Node.js processes with --inspect-brk debugging enabled, manages debug ports automatically, and exposes comprehensive debugging tools including breakpoint management, step-through execution, call stack inspection, and expression evaluation in debug contexts. Built with TypeScript and the chrome-remote-interface library, it handles the complexities of debugger attachment, execution state management, and provides both MCP tools for debugging operations and resources for session state monitoring, making it valuable for AI-assisted code debugging, automated testing workflows, and educational scenarios where agents need to understand code execution flow.
