MCP.Pizza Chef: web-infra-dev

This tool connects your AI assistant to Rsdoctor, a build-analysis tool used by websites and apps built with popular JavaScript tools such as Next.js, Nuxt, Storybook, and Docusaurus. Once connected, you can ask your assistant to explain why a website is taking too long to build, which files are making the finished product too large, or whether duplicate code has snuck into the output. It works with projects built on the Rspack or webpack build systems and is aimed at people who maintain or troubleshoot a website's technical build process.

rsdoctor FAQ

Can I use this to figure out why my website takes forever to build?
Yes — Rsdoctor examines the build process step by step and can point out which part, such as a specific plugin or dependency, is slowing things down, and your AI assistant can explain the results in plain language.
Can I use this to shrink my website's file size?
Yes — it can identify duplicate packages and oversized files that are bloating what gets sent to visitors' browsers, so you know exactly what to trim.
Do I need to know how to code to use this?
You will need some familiarity with how your website's build system works, since Rsdoctor is built for projects that already use Rspack or webpack-based tools like Next.js, Rsbuild, or Rspress.
Do I need an API key or paid account to use this?
No API key or paid account is mentioned in the setup — it runs alongside the build tools your project already uses.
Which AI assistants can I use this with?
The maker does not list specific assistants by name, but it is built to work with any AI assistant that supports the Model Context Protocol, which includes Claude and similar assistants such as ChatGPT and Gemini when connected through an MCP-compatible client.
How hard is it to set up?
Setup takes some developer know-how — you will typically add it to a project that already runs on Rspack or webpack and configure it as part of your existing build tooling, rather than a simple one-click install.
Does this work with Next.js?
Yes — Rsdoctor is compatible with Next.js as well as other popular tools such as Nuxt, Docusaurus, Storybook, and Modern.js.
Will this slow down my actual build process?
Rsdoctor is designed to analyze builds you are already running, so it adds an analysis step rather than replacing your normal build.
