## Description
An MCP server that provides build analysis and optimization recommendations for Rspack projects.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "rsdoctor": {
    "command": "npx",
    "args": ["-y","rsdoctor"]
  }
}
```

Rsdoctor is a build analyzer tailored for projects built with [Rspack](https://rspack.rs/).

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](https://rsdoctor.rs/guide/start/migration-v2) for details.

## 🔥 Features

- **Compilation Visualization**: Rsdoctor visualizes the compilation behavior and time consumption, making it easy to view build issues.

- **Multiple Analysis Capabilities**: Rsdoctor supports build artifact, build-time analysis, and anti-degradation capabilities:
  - Build artifact support for resource lists and module dependencies, etc.
  - Build-time analysis supports Loader, Plugin, and Resolver building process analysis
  - Build rules support duplicate package detection and ES Version Check, etc.

- **Support Custom Rules**: In addition to built-in build scan rules, Rsdoctor also supports users adding custom component scan rules based on the build data of Rsdoctor.
