How to install Butterbase Skills in Grok Build

grok plugin install butterbase-ai/butterbase-skills --trust
✓ Install-checked in Grok Buildchecked Oct 18, 2026

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

Skills work, MCP part needs manual setup. Grok loads Butterbase Skills's skills and commands, but not its MCP server: it needs settings that Claude Code asks for when you install it (userConfig), and Grok doesn't ask for them. Add the server yourself:

grok mcp add butterbase https://api.butterbase.ai/mcp -H 'Authorization: Bearer ${BUTTERBASE_API_KEY}'

Set the variable shown in ${…} in your shell before starting Grok (Grok fills it in when it loads the server).

Then start a new session or press r in /mcps. If it asks you to sign in, select it in /mcps and press i.

What we checked: on Oct 18, 2026 it installed with grok 1.0.62 and Grok found 47 skills, 34 slash commands. That's an install check only: we haven't run it in a live Grok session.

What it contains

Skills (25)
