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

Option 1: Using local build

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

      "command": "npx",
      "args": ["-y", "shadcn-ui-mcp-server"]
    }
  }
}

Windsurf Configuration

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

{
  "mcpServers": {
    "shadcn-ui-server": {
      "command": "npx",
      "args": ["-y", "shadcn-ui-mcp-server"]

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.
