What is MCP Node.js Debugger?
The MCP Node.js Debugger is a tool that integrates with Cursor and Claude Code to provide runtime debugging capabilities for Node.js applications. It allows developers to set breakpoints, inspect variables, and step through code execution directly within these AI-assisted coding environments.
How to use MCP Node.js Debugger?
To use the debugger, first add the MCP server configuration to Cursor or Claude Code. Then, run your Node.js server in debug mode (using the --inspect flag). Finally, ask Cursor or Claude Code to debug your Node.js server at runtime by setting breakpoints or inspecting variables.
