Basecoat MCP Server

Story

While building my hobby project — turning old devices into a Digital Photo Frame — I struggled with UI components. I wanted to use Basecoat CSS, the HTML port of ShadCN UI, but there was no MCP server to easily pull components and docs into AI-assisted coding.

So I built one.
This is my first MCP server, and it’s here to make working with Basecoat (and ShadCN-style components) effortless for everyone. Feedback and contributions are welcome!

A Model Context Protocol (MCP) server that provides programmatic access to Basecoat CSS components and their usage documentation. This server allows AI assistants to help developers build HTML interfaces using the Basecoat CSS framework.

Features

• 30+ Component Variants: Access to buttons, inputs, cards, dialogs, tabs, and more.
• Usage Documentation: Complete implementation guides with examples for each component.
• Setup Scripts: Get CDN links and theme switching code instantly.
• Search & Discovery: Find components by name or category.
• Accessibility Ready: All components include ARIA attributes and semantic HTML.

Tech Stack

• Node.js - JavaScript runtime environment
• @modelcontextprotocol/sdk - For creating the MCP server

Installation

1. Clone this repository:

   git clone https://github.com/Sorbh/basecoat-ui-mcp.git
   cd basecoat-mcp-server
   

2. Install dependencies:

   npm install
   

MCP Configuration

You can run this server either by using npx (if the package is published on npm) or by cloning the repository for local development.

Using NPX (Recommended)

This method is the easiest way to get started and doesn't require cloning the repository.

Claude Desktop

Update your claude_desktop_config.json:

{
  "mcpServers": {
    "basecoat-ui": {
      "command": "npx",
      "args": ["-y","basecoat-ui-mcp"]
    }
  }
}

Other MCP Clients

Configure the server to run:

npx basecoat-ui-mcp

Using Git Clone (Local Development)

For local development or if you want to modify the server:

1. Clone and setup:

   git clone https://github.com/Sorbh/basecoat-ui-mcp.git
   cd basecoat-ui-mcp
   npm install
   

2. Claude Desktop Configuration:

   {
     "mcpServers": {
       "basecoat-ui": {
         "command": "node",
         "args": ["/path/to/basecoat-ui-mcp/server.js"],
         "cwd": "/path/to/basecoat-ui-mcp"
       }
     }
   }
   

   Replace /path/to/basecoat-ui-mcp with the actual path where you cloned the repository.

3. Other MCP Clients:

   cd /path/to/basecoat-ui-mcp
   node server.js
