Enables real-time debugging of production Node.js applications by extracting live variable values directly from the runtime.
return0 provides an MCP (Model Context Protocol) server designed for real-time debugging of production Node.js applications, including those built with Next.js and deployed on platforms like Vercel. It allows developers to connect to live variables, observe execution flow, and understand runtime behavior directly within the Cursor IDE. By reading source files, performing TypeScript AST analysis to correct line numbers, and connecting to the running production application, it accurately retrieves live variable values, types, and timestamps from your code.
