2025-03-22
The `@hyperdrive-eng/mcp-nodejs-debugger` MCP server plugin lets Claude Code debug Node.js code at runtime. This article demonstrates debugging a Node.js app connecting to MongoDB Atlas, showcasing a runtime connection error. By setting breakpoints within Claude Code and executing custom JavaScript, developers can inspect MongoDB config variables to pinpoint issues like incorrect credentials or unauthorized IPs. The solution involves using a local MongoDB instance or correctly configuring MongoDB Atlas network access and credentials.
