10 LLM Agents Every Small Business Can Run on Self-Hosted n8n

Description and use

Ten simple n8n workflows using LLMs that automate key business tasks while minimizing hallucinations and keeping human oversight.

Problem

Small businesses need simple, reliable ways to leverage LLMs without complex agent frameworks.

Outcome

Ten reusable LLM‑powered n8n workflows that automate key business functions while minimizing hallucinations and keeping humans in the loop for outbound actions.

Workflow

• Trigger via webhook or schedule
• Build prompt with strict system prompt and JSON output contract
• Call LLM via HTTP Request to /chat/completions with JSON mode and 3 retries
• Parse response with safe JSON.parse and fallback
• Act: send to Slack, Sheets, CRM, or webhook response

Evidence

Most useful "agents" for a small business are one structured call inside a workflow you already trust.

Source

Ask for JSON and say what to do when data is missing ("use null, never guess"). That one line removes most hallucinations in extraction tasks.

Source

Put humans on outbound actions. Draft, don't auto-send.
