Basecoat UI

Official registry Productivity

Basecoat UI 1.0 components (shadcn/ui look in plain HTML + Tailwind) with usage docs and setup.

What can you do with Basecoat UI?

Basecoat 1.0.2: All markup follows the 1.0 API (class="btn" data-variant="outline", .field, method-based JS).
90+ Component Variants: Buttons, fields, input groups, cards, dialogs, command menus, drawers, charts and more.
Usage Documentation: Implementation guides for 30 components, including JS requirements and 0.x migration notes.
Setup Scripts: CDN links for any style pack (Vega, Nova, Maia, Lyra, Mira, Luma, Sera, Rhea) and the theme script.
Search & Discovery: Find components by name or category.
Accessibility Ready: All components include ARIA attributes and semantic HTML.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package basecoat-ui-mcp

Claude Code

claude mcp add basecoat-ui -- npx -y basecoat-ui-mcp@2.0.1

JSON configuration (Claude Desktop, Cursor, VS Code)

{
    "mcpServers": {
        "basecoat-ui": {
            "command": "npx",
            "args": [
                "-y",
                "basecoat-ui-mcp@2.0.1"
            ]
        }
    }
}

Basecoat MCP Server

Give your AI assistant the full Basecoat UI component library (the shadcn/ui look in plain HTML + Tailwind, no React), so it writes correct Basecoat markup instead of guessing class names.

Kept in sync with Basecoat releases. Basecoat 1.0.2 shipped with breaking API changes; this MCP was updated to it the same day.

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

Basecoat 1.0.2: All markup follows the 1.0 API (class="btn" data-variant="outline", .field, method-based JS).
90+ Component Variants: Buttons, fields, input groups, cards, dialogs, command menus, drawers, charts and more.
Usage Documentation: Implementation guides for 30 components, including JS requirements and 0.x migration notes.
Setup Scripts: CDN links for any style pack (Vega, Nova, Maia, Lyra, Mira, Luma, Sera, Rhea) and the theme script.
Search & Discovery: Find components by name or category.
Accessibility Ready: All components include ARIA attributes and semantic HTML.

Quick Start

No install needed: every client runs the server with npx.

Claude Code

claude mcp add basecoat-ui -- npx -y basecoat-ui-mcp

Claude Desktop

Add to claude_desktop_config.json:

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

Cursor

Click Install in Cursor above, or add to ~/.cursor/mcp.json:

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

VS Code (GitHub Copilot)

Click Install in VS Code above, or add to .vscode/mcp.json:

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

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

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

Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.basecoat-ui]
command = "npx"
args = ["-y", "basecoat-ui-mcp"]

Other MCP clients

Run npx -y basecoat-ui-mcp as a stdio server.

Try it

Ask your assistant something like:

Build a sign-up page with Basecoat: a card with GitHub/Google buttons, email and password fields, and a dark mode toggle.

It will call get_setup, pull the matching components and usage docs, and return HTML that uses the real Basecoat 1.0 API.

Local Development

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

Point your client at the local copy:

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

Upgrading from 1.x of this MCP

Version 2.0.0 of this MCP targets Basecoat 1.0.2, which has breaking changes from Basecoat 0.3.x:

Variant classes became data attributes: btn-outline → class="btn" data-variant="outline", btn-sm-icon → data-size="icon-sm".
The .form wrapper was removed; wrap each label and control in <div class="field">.
Document events (basecoat:toast, basecoat:sidebar, basecoat:theme) were replaced by methods: toaster.toast(), sidebar.toggle(), window.basecoat.theme.toggle().
dialog-alert was renamed to alert-dialog.

If your project still has 0.x markup, load Basecoat's compatibility stylesheet after Basecoat while you migrate (@import "basecoat-css/compat";). See style-guide.md for the full migration guide.
