Human-in-the-Loop Automation with n8n
summary
Builds a working Gmail and Google Calendar agent inside n8n visual canvas that connects Gmail, Calendar, Slack and OpenRouter (Sonnet 4.6) as the LLM, uses simple memory and exposes tools as callable nodes, and enforces safety with an intercepting human review node that blocks destructive actions until approved. Demonstrates publishing, scheduled hourly runs, webhook/API use, MCP integration, and live executions with logs; demos run and succeed after minor setup hiccups and credential/version checks.
