Fudge Plugin for Grok Build

Fudge gives AI coding tools website references they can search and inspect while building. It captures the details behind each website, including typography, colors, layout, components, spacing, borders, shadows, gradients, media, and page context.

This plugin connects Grok Build to Fudge's hosted MCP server and includes guidance for using captured website evidence in design research, critique, and implementation.

Installation

In Grok Build, open /plugin, search for Fudge, and install the plugin.

On first connection, Grok opens Fudge's authorization flow in the browser. Sign in at design.withfudge.com and approve access. No API key or local credential file is required.
