How to install Claude For Legal in Grok Build

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

grok plugin marketplace add anthropics/claude-for-legal

2. Install the plugin:

grok plugin install commercial-legal@anthropics/claude-for-legal --trust

✓ Install-checked in Grok Buildchecked Oct 18, 2026

Needs your own API key or sign-in to work fully. We check that it installs and loads, not your account.

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.

This repo's marketplace has 13 plugins; we checked commercial-legal, privacy-legal, product-legal. Install another the same way: grok plugin install <name>@anthropics/claude-for-legal --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 anthropics/claude-for-legal, then select commercial-legal and press i.

Command format: Grok Build's plugin guide

Needs a sign-in. Its MCP server is hosted by the vendor, and most hosted MCP servers ask you to sign in the first time. In Grok, open /mcps, select the server and press i to sign in.

What we checked: on Oct 18, 2026 it installed with grok 1.0.62 and Grok found 28 skills, 2 subagents. That's an install check only: we haven't run it in a live Grok session.
