Claude Desktop Configuration

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": "npx",
      "args": ["@heilgar/shadcn-ui-mcp-server"]
    }
  }
}

Windsurf Configuration

Add this to your ./codeium/windsurf/model_config.json:

{
  "mcpServers": {
    "shadcn-ui-server": {
      "command": "npx",
      "args": ["@heilgar/shadcn-ui-mcp-server"]
    }
  }
}

Cursor Configuration

Add this to your .cursor/mcp.json:

{
  "mcpServers": {
    "shadcn-ui-server": {
      "command": "npx",
      "args": ["@heilgar/shadcn-ui-mcp-server"]
    }
  }
}

Development and Debugging

Local Development

Install dependencies:

npm install

Build the server:

npm run build

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector for debugging:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser, allowing you to:

Monitor MCP communication
Inspect tool calls and responses
Debug server behavior
View real-time logs

This project is built using the following tools and libraries:

Model Context Protocol TypeScript SDK - The official TypeScript SDK for MCP servers and clients
MCP Inspector - A debugging tool for MCP servers
Cheerio - Fast, flexible, and lean implementation of core jQuery designed specifically for the server
