Summary
This server hooks into Rsdoctor's build analysis engine to help you diagnose and optimize Rspack and webpack projects through conversation. It exposes your project's compilation data, loader and plugin performance metrics, bundle composition, and duplicate dependency detection directly to Claude. You can ask questions about build bottlenecks, get recommendations on which loaders are slowing you down, or identify bloated modules without opening the visual dashboard. It works with any Rspack or webpack based setup, including Next.js, Nuxt, Rsbuild, and Modern.js. If you're already using Rsdoctor for build analysis and want to query that data conversationally rather than clicking through reports, this brings those insights into your chat workflow.

Rsdoctor
English | 简体中文
Rsdoctor is a build analyzer tailored for projects built with Rspack.
Rsdoctor is committed to being a one-stop, intelligent build analyzer that makes the build process transparent, predictable, and optimizable through visualization and smart analysis, helping development teams precisely identify bottlenecks, optimize performance, and improve engineering quality.
For webpack projects, continue using Rsdoctor 1.x or migrate to Rspack. See the migration guide for details.

🙏 Credits
Some of the implementation of Rsdoctor refers to the excellent projects in the community, and we would like to thank them:
- bundle-stats is an excellent tool for analyzing build artifacts, and Rsdoctor is inspired by it in terms of build analysis.
- webpack-bundle-analyzer is a classic tool for analyzing Webpack, and Rsdoctor is inspired by it in terms of build artifact analysis. Rsdoctor also uses its classic treemap visualization.
- Statoscope is an excellent tool for analyzing build artifacts, and Rsdoctor is inspired by it in terms of build analysis.
- Webpack Team and Community have created an excellent bundling tool and a rich ecosystem.
- vite-plugin-inspect has inspired Rsdoctor's exploration of build process analysis.
