How I AI · Monday, October 26, 2026
To bridge the gap between design and engineering, Reddit created a custom Model Context Protocol (MCP) that maps Figma design tokens, button sizes, and components directly to production code and GitHub. This allows AI tools like Cursor to generate production-ready code based on design inputs and automated feedback.
“And so here you have every single token, component, surface, journey, that we know of across RPL, Reddit Product Language.”
“Well, the team. We're going with our team. ... That's right. Yeah, so right here we got it hooked up, this Proto MCP Ultra, and it's basically like looking for... What are you feeding it? And and then it's finding tokens, components, and examples to write that prod-shaped code.”
