shadcn-ui MCP Server

MCP server for shadcn/ui component references

This is a TypeScript-based MCP server that provides reference information for shadcn/ui components. It implements a Model Context Protocol (MCP) server that helps AI assistants access shadcn/ui component documentation and examples.

Features

Tools

  • list_shadcn_components - Get a list of all available shadcn/ui components
  • get_component_details - Get detailed information about a specific component
  • get_component_examples - Get usage examples for a specific component
  • search_components - Search for components by keyword

Functionality

This server scrapes and caches information from:

  • The official shadcn/ui documentation site (https://ui.shadcn.com)
  • The shadcn/ui GitHub repository

It provides structured data including:

  • Component descriptions
  • Installation instructions
  • Usage examples
  • Props and variants
  • Code samples

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "shadcn-ui-server": {
      "command": "/path/to/shadcn-ui-server/build/index.js"
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
