I've recently automated a large portion of my Rails performance audits. In this tutorial, I'll describe how to configure an AI-powered PG performance debugging. We will cover using LLMs with custom MCP (model context protocol) n8n integration. We will also discuss the legal and security implications of connecting AI to the production database. There’s also a live demo available!

Here’s how I use Claude Code to develop Ruby on Rails applications. Mostly medium sized ones that have been around for a while. No green-field, everything-is-possible, agents-go-wild vibe coding for me. I’ll leave that to others.
