October Themes MCP Server

October Themes MCP Server

An MCP server that injects curated design system themes into AI-generated UI. Works with Claude, ChatGPT, Cursor, VS Code Copilot, Windsurf, and any tool that supports the Model Context Protocol.

Stop getting generic-looking AI UI. This server gives your AI coding tool access to 1000+ handcrafted design systems — color palettes, typography, component styles, animations, and bold design rules — so every generated interface has a distinct, polished aesthetic.

Quick Start

Add to your AI tool — no API key needed, completely free.

Claude Desktop / Claude Code — add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "october-themes": {
      "command": "npx",
      "args": ["-y", "@october-dev/themes-mcp"]
    }
  }
}

Cursor — add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "october-themes": {
      "command": "npx",
      "args": ["-y", "@october-dev/themes-mcp"]
    }
  }
}

VS Code Copilot — add to .vscode/mcp.json:

{
  "servers": {
    "october-themes": {
      "command": "npx",
      "args": ["-y", "@october-dev/themes-mcp"]
    }
  }
}

Windsurf — add to ~/.windsurf/mcp.json:

{
  "mcpServers": {
    "october-themes": {
      "command": "npx",
      "args": ["-y", "@october-dev/themes-mcp"]
    }
  }
}

Use it

Just ask your AI:

• "Get me a theme for this website"
• "Inject a mobile app theme and build the settings screen"

The AI will call the MCP tools automatically.

Tools

| Tool | Description | |------|-------------| | get_theme | Get a weighted-random design system theme, optionally filtered by platform (desktop-web, mobile-app, game). Returns prompt-ready markdown. | | get_theme_by_id | Fetch a specific theme by its ID/slug. |

How It Works

1. You ask your AI to build UI
2. The AI calls get_theme to get a design system
3. The theme (colors, typography, spacing, component styles, animations) becomes part of the AI's context
4. All generated UI follows that design system — no more generic Bootstrap-looking output

Themes are curated by the October team — the AI-native canvas for building apps. Each theme includes:

• Complete color palette (8+ semantic colors with hex values)
• Typography system (fonts, sizes, weights)
• Component styles (buttons, cards, inputs with real Tailwind classes)
• Effects & animations (shadows, gradients, transitions)
• Non-Genericness Rules — mandatory bold design choices that prevent bland output

Platforms

• desktop-web — Websites, dashboards, SaaS apps
• mobile-app — iOS/Android apps (includes navigation, safe areas, haptics)
• game — Browser games (includes lighting, particles, HUD styling)
