vite-plugin-vue-mcp

Vite plugin that enables a MCP server for your Vue app to provide information about the component tree, state, routes, and pinia tree and state.

Installation 📦

pnpm install vite-plugin-vue-mcp -D

Usage 🔨

// vite.config.ts
import { VueMcp } from 'vite-plugin-vue-mcp'

export default defineConfig({
  plugins: [VueMcp()],
})

Then the MCP server will be available at http://localhost:[port]/__mcp/sse.

If you are using Cursor, create a .cursor/mcp.json file in your project root, this plugin will automatically update it for you. For more details about the MCP, check the official Cursor documentation.
