Using Figma MCP Server to Give Claude Code and Cursor Accurate Design Context for UI Work
Problem / Context
Claude Code and Cursor implementing UI from screenshots or verbal descriptions produce layouts that visually approximate the design but miss spacing, typography, and component structure. The agents are guessing.
Solution
Connect the Figma Dev Mode MCP server to Claude Code and Cursor. The MCP server exposes Figma design tokens, component specs, and layout measurements as structured data the agent can query. When working on a UI component, point the agent to the corresponding Figma frame using the frame URL. The agent calls the MCP's get_figma_data tool to retrieve exact values: padding (16px, not 'some padding'), font weight (500, not 'medium'), color (#1A1A1A, not 'dark gray'), and component hierarchy. Include the retrieved design tokens in the implementation prompt. Commit a rules configuration file to the repo that defines Figma MCP behavior: which frames map to which components, which design tokens to prefer when conflicts arise, and how to handle missing values. TypeScript types are generated from the design token schema for compile-time validation.
Result
UI implementations match Figma designs pixel-accurately on first attempt. Iteration cycles on spacing and typography reduced from 3-4 rounds to zero. GitHub review time for UI PRs cut in half.
