Design Style MCP Server

A Model Context Protocol (MCP) server that provides design style intelligence for AI content generation. Ships with 30 curated design styles — each with color palettes, typography, mood tokens, visual directives, and negative prompts ready for image/video generation pipelines.

No AI inference — pure deterministic scoring against style characteristics.

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "design-style": {

}

How It Works

recommend_style

Given a brand description, campaign objective, target demographic, and optional season, the server scores all 30 styles against their characteristics (objectives, demographics, industries, moods, seasonal fit) and returns the top match with alternatives.

Input:  { objective: "product_launch", demographic: "gen_z", brand: "streetwear" }
Output: { style: "neo-brutalism", reasoning: "...", alternatives: [...] }

get_style

Given a style slug, returns structured tokens extracted from the style's prompt file:

Input:  { style: "cyberpunk" }
Output: { name, description, colors, typography, mood, promptAdditions, negativePrompt, reference }

Configuration

| Env Var | Default | Description | | -------------------- | --------------------------------------- | ------------------------------------------------- | | DESIGN_STYLES_PATH | ./design-styles (relative to package) | Override path to the design-styles data directory |

Architecture

• Transport: stdio (standard MCP protocol)
• Data: 30 style prompt files + descriptions index (plain text, bundled)
• Scoring: Deterministic fuzzy matching — no AI inference, no network calls
• Caching: Prompt files are cached in-memory after first read
• Dependencies: Only @modelcontextprotocol/sdk and zod

Development

# Development server (auto-reload)
npm run dev

# Type check
npx tsc --noEmit

# Build
npm run build

Adding a New Style

1. Add the slug to DESIGN_STYLE_SLUGS in src/styles.ts
2. Add characteristics (objectives, demographics, industries, moods) to STYLE_CHARACTERISTICS
3. Add a description line to design-styles/descriptions.txt
4. Create a prompt file at design-styles/prompts/{slug}.txt
