n8n AI Agent Template: Memory, Tools & Guardrails Demo

This n8n workflow is an educational reference template showing how to build production-grade AI agents. It demonstrates a working restaurant menu assistant example that uses Postgres-backed conversation memory, callable tool workflows, structured output parsing with auto-fixing, and a guardrail node that requires Slack approval before risky actions execute. Error handling and control-flow nodes round out the pattern. Perfect for n8n builders and AI automation developers who want a battle-tested blueprint for combining memory, tools, and safety checks in their own custom agents instead of starting from scratch.
