Shadcn UI MCP Server v4 Details

Shadcn UI v4 MCP Server is an advanced MCP (Model Context Protocol) server designed to give AI assistants comprehensive access to shadcn/ui v4 components, blocks, demos, and metadata. It enables multi-framework support (React, Svelte, Vue, and React Native) with fast, cache-friendly access to component source code, demos, and directory structures, empowering AI-driven development workflows. The project emphasizes production-readiness with Docker Compose, SSE transport for multi-client deployments, and smart caching to optimize GitHub API usage while providing rich metadata and usage patterns for rapid prototyping and learning across frameworks.

Use Case

This MCP server enables AI assistants to learn from and interact with shadcn/ui v4 components across multiple frameworks. It provides a single integration point to fetch component source code, demos, blocks, and metadata, enabling use cases such as AI-powered UI generation, cross-framework comparison, and rapid prototyping. Example scenarios include: retrieving React and Vue implementations for a given component, exploring blocks like dashboards or forms, and fetching metadata about dependencies and configurations. Code examples from the docs illustrate how to run and configure the server, switch frameworks, and connect editors or agents via SSE transport for real-time interaction.
