Norrly API & MCP server

Design tokens as a service · free tier · no credit card

Everything Norrly measures — exact colors, typography, layout values and complete vibe-coding prompts from 350+ of the best-designed websites — is available programmatically: as a REST API for your own apps, and as an MCP server that plugs straight into Cursor, Claude and other MCP-capable tools.

MCP server (Cursor, Claude & friends)

Add Norrly to your MCP configuration and your AI assistant can search the library, fetch measured design tokens and pull complete style prompts — mid-conversation. In Cursor, add to .cursor/mcp.json (or Settings → MCP):

{
  "mcpServers": {
    "norrly": {
      "url": "https://norrly.io/mcp",
      "headers": { "Authorization": "Bearer nly_YOUR_KEY" }
    }
  }
}

Then ask things like "get Linear's design tokens from Norrly and restyle my hero section" or "find three dark fintech references and build me a page in that language".

Tools exposed:

search_sitesSearch 350+ curated sites by text, category or style tag. Returns slugs.

get_design_tokensMeasured tokens for one site: colors, fonts, H1/H2/body scale, max-width, section padding, radius, button specs, theme.

get_style_prompt API keyThe complete founding prompt that recreates the site's design language — paste-ready for Lovable, Cursor, v0 or Bolt.
