Cortexdb plugin for Grok Build
AI memory and a knowledge graph in one SQLite file. Pure Go: vectors, RAG, agent memory, RDF/SPARQL, Cypher, 80+ MCP tools. Works without an embedding model.
How to install Cortexdb in Grok Build
1. Add this repo as a plugin marketplace in Grok Build (once per computer):
grok plugin marketplace add liliang-cn/cortexdb2. Install the plugin:
grok plugin install cortexdb@liliang-cn/cortexdb --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.
This repo's marketplace has 2 plugins; we checked cortexdb. Install another the same way: grok plugin install <name>@liliang-cn/cortexdb --trust (names under 'What it contains'). 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 liliang-cn/cortexdb, then select cortexdb and press i.
Command format: Grok Build's plugin guide
Runs a local MCP server (with npx, uvx or similar), so that tool needs to be installed, for example Node.js for npx.
What we checked: on Oct 18, 2026 it installed with grok 1.0.62 and Grok found 14 skills, 13 slash commands. That's an install check only: we haven't run it in a live Grok session.
