Figma Capture Script Installation
Guide for adding Figma's capture script to a web project so pages can be captured to Figma without Playwright injection.
Background
Figma MCP's generate_figma_design tool captures a rendered web page and converts it into editable Figma layers. The capture requires Figma's serializer script loaded on the page. Two approaches:
- Script in HTML (this skill) - embed the script for dev-only use. Simpler, faster.
- Playwright injection (via
/dev-figma-capture) - inject at runtime. No source changes but heavier.
The Script
<script src="https://mcp.figma.com/mcp/html-to-design/capture.js" async></script>
What it does:
- Walks entire DOM tree, reads computed styles, layout, fonts, images
- Serializes everything into JSON (~several MB for typical pages)
- Listens for capture parameters via URL hash fragment
- POSTs serialized data to Figma's API when triggered
Installation Guidance
Add the script to the project's HTML only in development mode. Never ship to production.
Recommended Pattern (React/Vite)
{process.env.NODE_ENV === 'development' && (
<script src="https://mcp.figma.com/mcp/html-to-design/capture.js" async />
)}
Important Notes
- Place in
<head> or end of <body>
- Loads asynchronously, minimal performance impact
- Never ship to production - serializes entire DOM structure
- After installation,
/dev-figma-capture can use the simpler URL fragment approach instead of Playwright
- The actual file edit should be done by the main agent based on the project's framework
