Overview

MCP NodeJS Debugger is a tool that allows developers to debug NodeJS applications at runtime using the Claude Code environment.

To use the MCP NodeJS Debugger, you need to add it to Claude Code, start your NodeJS server in debug mode, and then ask Claude Code to help you debug any runtime errors.

Runtime debugging of NodeJS applications - Integration with Claude Code for enhanced debugging capabilities - Ability to set breakpoints and inspect variables during execution

Debugging runtime errors in NodeJS applications.
Inspecting variable states and application flow during execution.
Assisting in resolving database connection issues in real-time.

Use these steps to connect MCP Node.js Debugger in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "mcp-nodejs-debugger-hyperdrive-eng": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-nodejs-debugger-hyperdrive-eng"
      ]
    }
  }
}
