Getting Started With n8n For AI Automation

First, what is n8n?

If you're not familiar with n8n yet, it's a workflow automation utility that allows us to use nodes to connect services quite easily. It's been the subject of quite a bit of Artificial Intelligence hype because it helps you construct AI Agents.

I'm going to be diving more into n8n, what it can do with AI, and how to use our AI Gateway to defend against some difficult AI threats today. My hope is that you can use this in your own labs to prove out some of these things in your environment.

How do you install it?

Well... It’s all node, so the best way to install it in any environment is to ensure you have node version 22 (on Mac, homebrew install node@22) installed on your machine, as well as nvm (again, for mac, homebrew install nvm) and then do an npm install -g n8n. Done! Really...That simple.
