{"type":"mcp_client","name":"mcp-nodejs-debugger","description":"This repository provides an MCP server, `@hyperdrive-eng/mcp-nodejs-debugger`, enabling Cursor or Claude Code to debug Node.js applications at runtime. It allows real-time inspection and debugging with simple setup instructions for both platforms.","category":"Developer Tools","language":"JavaScript","stars":301,"forks":5,"owner":"hyperdrive-eng","github_url":"https://github.com/hyperdrive-eng/mcp-nodejs-debugger","homepage":"https://npmjs.com/package/@hyperdrive-eng/mcp-nodejs-debugger","setup":"## Setup\n\n### Cursor\n\n1.  Add to Cursor (`~/.cursor/mcp.json`):\n\n    ```diff\n    + {\n    +   \"mcpServers\": {\n    +   \"nodejs-debugger\": {\n    +      \"command\": \"npx\",\n    +       \"args\": [\"@hyperdrive-eng/mcp-nodejs-debugger\"]\n    +     }\n    +   }\n    + }\n    ```\n\n2.  Run a Node.js server in [debug mode](https://nodejs.org/en/learn/getting-started/debugging) (i.e. with the `--inspect` flat):\n\n    ```sh\n    node --inspect {file.js}\n    ```\n\n3.  Ask Cursor to debug your Node.js server at runtime\n\n### Claude Code\n\n1.  Add to Claude Code:\n\n    ```sh\n    claude mcp add nodejs-debugger npx @hyperdrive-eng/mcp-nodejs-debugger\n    ```\n\n2.  Start Claude Code:\n\n    ```sh\n    claude\n    ╭───────────────────────────────────────────────────────╮\n    │ ✻ Welcome to Claude Code research preview!            │\n    │                                                       │\n    │   /help for help                                      │\n    │                                                       │\n    │   Found 1 MCP server (use /mcp for status)            │\n    ╰───────────────────────────────────────────────────────╯\n    ```\n\n3.
