Obsidian Second Brain plugin for Grok Build
Persistent memory for Claude Code, Codex and 6 other AI agents, stored as plain markdown in your Obsidian vault.

How to install Obsidian Second Brain in Grok Build
grok plugin install eugeniughelbur/obsidian-second-brain --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.
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
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 48 skills, 48 slash commands. That's an install check only: we haven't run it in a live Grok session.
