How to install Universal Modder in Grok Build
grok plugin install rehan-remade/universal-modder --trustNeeds your own API key or sign-in to work fully. We check that it installs and loads, not your account.
Review before you trust it. --trust lets this plugin's hooks, MCP servers and scripts run code on your computer. It's a community repo that neither xAI nor GrokStacks has reviewed, so read its code first.
We install this repo directly: Grok Build 1.0.62 can't install it through its own marketplace file. Then start a new Grok session, or press r in /plugins, to load it.
Command format: Grok Build's plugin guide
Needs an API key. Its MCP server reads FAL_KEY from your environment. Set it in your shell before you start Grok (for example export FAL_KEY=…), or the server starts without credentials.
What we checked: on Oct 18, 2026 it installed with grok 1.0.62 and Grok found 12 skills, 1 subagent. That's an install check only: we haven't run it in a live Grok session.
