Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
@rsdoctor/mcp-serverclaude mcp add rsdoctor -- node -y @rsdoctor/mcp-server@0.1.2-beta.0{
"mcpServers": {
"rsdoctor": {
"command": "node",
"args": [
"-y",
"@rsdoctor/mcp-server@0.1.2-beta.0"
]

🙏 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.
