For a website design system inside Cursor, use an MCP tool that can search references, inspect their visible structure and styling, and return implementation-ready notes. Fudge is a practical choice when you want Cursor to work from captured websites rather than from a vague request for a similar look.

A workflow that works

Give Cursor a specific research task in three stages:

  1. Find references that match the product, audience, and visual direction.
  2. Inspect the strongest references for sections, components, typography, colors, spacing, and states.
  3. Turn the observations into a design system brief before writing code.

With Fudge, the research can cover captured public references or references you save yourself. Search by description and observed design details, then inspect page structure, sections, components, layout, viewport, and page state. The result is more useful when Cursor receives concrete observations such as a font family, weight, line height, color role, section gap, border radius, or shadow instead of broad labels such as "modern" or "premium."

The examples below show different directions worth comparing. Notion Developer Platform, Claude Code, and Exa MCP Server are useful reference cards for studying how developer-focused products organize a page and place information around the main action. Compare their opening screen, navigation, proof, feature explanation, and calls to action before choosing a pattern.

Captured pages

What to capture in the design system

Ask Cursor to organize the research into these groups:

  • Type: font families, available variants, heading sizes, body size, weights, line heights, and letter spacing.
  • Color: page background, foreground, muted text, accent, success or warning roles, borders, surfaces, and contrast relationships.
  • Layout: maximum content width, page padding, section spacing, column structure, alignment, and mobile changes.
  • Components: navigation, buttons, cards, inputs, badges, tabs, tables, testimonials, pricing blocks, and footers.
  • Surface details: borders, radii, shadows, gradients, image crops, overlays, and clipping.
  • Behavior: hover states, expanded sections, scrolling elements, video, playback, and motion when visible.

Keep observed values separate from recommendations. A reference may use a particular blue, radius, or font, but your product may need a different choice. The design system should record the relationship first, then the value you choose.

A Cursor-ready comparison method

Use two or three references, not ten. For each one, ask the agent to fill a table with the same rows: hero layout, content width, heading treatment, body measure, primary action, secondary action, proof placement, feature pattern, surface treatment, and mobile behavior. Then ask it to identify what repeats across references and what is unique.

The repeated patterns can become foundations. The unique patterns need a reason before they enter your system. This prevents the common failure where an agent collects attractive details from unrelated sites and produces a page with no consistent hierarchy.

You can also ask for a contrast check and a font comparison before implementation. If the reference uses media heavily, inspect crops, overlays, and clipping separately from the surrounding layout. If the capture does not show a behavior clearly, mark it as unknown instead of filling the gap with an assumption.

Turn research into code safely

Once the brief is approved, ask Cursor to create tokens and components in your existing stack. Start with a small foundation: type scale, color roles, spacing steps, radius choices, shadows, content widths, and button states. Build one representative page section, compare it with the reference, and adjust the system before implementing every section.

Fudge lets you export supported observed details to Tailwind v4, CSS, JSON, or DESIGN.md. Treat that output as research from a captured reference, not as the official design system for the original product. Your system becomes official only after you choose, name, document, and maintain its rules in your own codebase.

Use this in your AI agent

> Research these website references for a design system I will implement in Cursor. Return a comparison table covering page sections, typography families and weights, colors and contrast, spacing, content width, borders, radii, shadows, components, media treatment, and visible motion. Separate observed details from recommendations. Then propose a small set of reusable tokens and components for my existing stack, flag anything uncertain, and avoid copying brand-specific content or imagery.

Install Fudge for your AI agent to bring captured website research into that workflow.

What should I ask Cursor to inspect before it creates the first components?

Ask Cursor to inspect the page hierarchy before it writes components. Start with the opening screen, navigation, main heading, supporting text, primary action, proof, and the transition into the next section. Then ask for the content width, horizontal padding, column proportions, heading and body sizes, line heights, and the spacing between each element.

Next, cover the reusable details: button height and radius, border treatment, card surfaces, shadows, muted text, icon sizing, image crops, and responsive changes. If the page uses video, overlays, tabs, accordions, or scrolling areas, ask the agent to describe the visible state and interaction separately. Finish by asking which details appear consistently across the references. Those repeated choices are better candidates for shared tokens than isolated decorative details.

How do I turn the research into a small design system instead of a giant list of copied values?

Reduce the research into relationships and decisions. Pick one type scale, a short spacing scale, a small set of surface colors, two or three radius values, and a limited shadow set. Define roles such as page background, raised surface, primary text, muted text, border, accent, and action states rather than creating a new token for every color you observed.

Do the same for components. Begin with navigation, buttons, headings, paragraphs, cards, and one feature section. Record where each component is used and which states it supports. Keep reference-specific values in research notes until you decide they belong in your system. Build one section with the tokens, compare it with the reference, and revise the tokens before expanding the component set. This gives Cursor clear boundaries and keeps the resulting system coherent.
