How to install Cartcut in Grok Build
1. Add this repo as a plugin marketplace in Grok Build (once per computer):
grok plugin marketplace add cartesiancs/cartcut2. Install the plugin:
grok plugin install cartcut-editing@cartesiancs/cartcut --trustReview 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.
Then start a new Grok session, or press r in /plugins, to load it.
Inside Grok Build: type /plugins, open the Marketplace tab, press a and add cartesiancs/cartcut, then select cartcut-editing and press i.
Command format: Grok Build's plugin guide
Skills work, MCP part needs manual setup. Grok loads Cartcut'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 with grok mcp add (see grok mcp add --help), using the server address and settings from the plugin's README.
What we checked: on Oct 19, 2026 it installed with grok 1.0.62 and Grok found 1 skill. That's an install check only: we haven't run it in a live Grok session.
