MCP Node js Debugger

MCP Node js Debugger is a Model Context Protocol (MCP) server that enables AI coding assistants to debug Node.js applications. It connects to the V8 Inspector protocol, exposing tools to set breakpoints, inspect scopes, and evaluate expressions.

Key Features of MCP Node js Debugger

• V8 Inspector Integration: Connects directly to the native Node.js debugger port (e.g. --inspect).
• Variable Scope Inspection: Allows AI assistants to inspect local variables, closures, and call stack parameters.
• Dynamic Breakpoints: Set and clear breakpoints inside files dynamically during execution runs.
• Expression Evaluation: Run JS expressions on active process scopes to debug variable states.

Benefits of Using MCP Node js Debugger

• AI-Guided Troubleshooting: Let AI analyze stack traces, inspect scope variables, and suggest bug fixes in real-time.
• Skip Complex Configs: Debug Node applications using conversational prompts instead of setting up IDE run configurations.
• Faster Error Resolution: Pinpoint the exact line of code causing variables to mismatch or throw errors.

To debug backend tests, developers can use MCP Node js Debugger to let AI assistants attach to node processes, inspect variables, and step through code.
