An MCP server that queries Rsdoctor local build analysis data through a Q&A interface. It exposes build artifact, dependency, bundle optimization, and build performance analysis information from the current project’s Rsdoctor data.
From the registry: An MCP server that provides build analysis and optimization recommendations for Rspack projects.
Install & configure
Prerequisites
- requiredInstall and configure an Rsdoctor pluginYour project must use an Rsdoctor plugin version >= 1.1.2 so the MCP server can read local build analysis data. Supported plugins mentioned are @rsdoctor/rspack-plugin and @rsdoctor/webpack-plugin. Follow the Rsdoctor Quick Start if not already configured.https://rsdoctor.rs/guide/start/quick-start/
- requiredEnable Rsdoctor local server outputEnsure Rsdoctor's local server is enabled. If your config sets disableClientServer: true, change it to disableClientServer: false.
- requiredRun a local build with Rsdoctor enabledGenerate the local build analysis data before using the MCP server. Do not start the build through the MCP client; run it separately.
$ npm run build

Please install the `rsdoctor` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install and configure an Rsdoctor plugin** — Your project must use an Rsdoctor plugin version >= 1.1.2 so the MCP server can read local build analysis data. Supported plugins mentioned are @rsdoctor/rspack-plugin and @rsdoctor/webpack-plugin. Follow the Rsdoctor Quick Start if not already configured. (https://rsdoctor.rs/guide/start/quick-start/)
- **Enable Rsdoctor local server output** — Ensure Rsdoctor's local server is enabled. If your config sets disableClientServer: true, change it to disableClientServer: false.
- **Run a local build with Rsdoctor enabled** — Generate the local build analysis data before using the MCP server. Do not start the build through the MCP client; run it separately. Run: `npm run build`
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@rsdoctor/mcp-server@latest"]
Note: Optional args supported by the server: --compiler <compiler-name> for multi-compiler projects to select which Rsdoctor dataset to analyze, and --port <port> to match a fixed Rsdoctor local server port. If using --port <port>, configure the same port in your Rsdoctor plugin, e.g. port: <port>. By default, Rsdoctor local server uses a random port.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: Optional args supported by the server: --compiler <compiler-name> for multi-compiler projects to select which Rsdoctor dataset to analyze, and --port <port> to match a fixed Rsdoctor local server port.
