How to install HippoRAG in Grok Build

1. Add this repo as a plugin marketplace in Grok Build (once per computer):

2. Install the plugin:

grok plugin install hipporag@OSU-NLP-Group/HippoRAG --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.

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 OSU-NLP-Group/HippoRAG, then select hipporag and press i.

Command format: Grok Build's plugin guide

Skills work, MCP part needs manual setup. Grok loads HippoRAG'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 18, 2026 it installed with grok 1.0.62 and Grok found 2 skills. That's an install check only: we haven't run it in a live Grok session.
