shadcn registry manager - MCP Server

This project provides an MCP (Model Context Protocol) server for the shadcn/ui component registry and CLI. It enables remote, programmatic, or containerized execution of shadcn CLI commands (such as init, add, etc.) that you would normally run locally, making it easy to automate, integrate, or run in cloud/dev environments. The MCP server can connect to both local and remote shadcn registries, providing a secure, extensible, and technical interface for automating project management tasks via AI or CLI agents.

What It Does

This MCP server exposes shadcn CLI operations as MCP tools, so you (or an AI agent) can:

• Initialize a project
• Add components from the shadcn registry including block components
• List and fetch registry items
• Run all shadcn CLI workflows remotely
• Supports both the official shadcn registry - https://ui.shadcn.com/r and custom/self-hosted registries follow this guide: https://ui.shadcn.com/docs/blocks

Usage

Docker

Run the MCP server in a container, mounting your project directory:

Add the following to your mcp.json file:

   "shadcn-registry-manager": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--mount",
        "type=bind,src=<your-project-path>,dst=/workspace",
        "-e", 
        "REGISTRY_URL=https://ui.shadcn.com/r",
        "-e", 
        "STYLE=new-york",
        "reuvenaor/shadcn-registry-manager"
      ],
    },

Docker mounting explanation:

• <your-project-path> - Is the path to your project directory.

  Example: /Library/Projects/shadcn-registry-manager/www

• /workspace - is the path to the workspace directory inside the container. (Don't change it, if you do, you must pass the same path as cwd param on every tool call)

Docker ENV Variables:

• REGISTRY_URL
  • option 1: https://ui.shadcn.com/r - The URL of the shadcn registry
  • option 2: http://localhost:3000>/r - The URL of your own registry server (follow this guide: https://ui.shadcn.com/docs/blocks)
• STYLE - is the style of the shadcn registry - new-york

npx

You can also run the MCP server using npx, which is convenient for local development or CI/CD pipelines.

Add the following to your mcp.json file:

  "shadcn-registry-manager": {
    "command": "npx",
    "args": [
      "@reuvenorg/shadcn-registry-manager"
    ],
    "env": {
      "REGISTRY_URL": "https://ui.shadcn.com/r",
      "WORKSPACE_DIR": "/Library/Projects/mcp-docker/www",
      "STYLE": "new-york"
    }
  }

Claude

You can also use the MCP server with Claude. Here are the configuration options:

Claude CLI Command:

claude mcp add --scope project shadcn-registry-manager npx @reuvenorg/shadcn-registry-manager -e REGISTRY_URL=https://ui.shadcn.com/r -e WORKSPACE_DIR=/Library/Projects/resume -e STYLE=new-york

Claude .mcp.json Configuration:

{
  "shadcn-registry-manager": {
    "type": "stdio",
    "command": "npx",
    "args": [

      "WORKSPACE_DIR": "/Library/Projects/resume",
      "STYLE": "new-york"
    }
  }
}

npx ENV Variables:

• WORKSPACE_DIR - The path to your project directory (mounted as the workspace)
• REGISTRY_URL
  • option 1: https://ui.shadcn.com/r - The URL of the shadcn registry
  • option 2: http://localhost:3000/r - The URL of your own registry server (follow this guide: https://ui.shadcn.com/docs/blocks)
• STYLE - is the style of the shadcn registry - new-york
