Automate Website Monitoring with GPT-4 Mini, MCP Tools & Multi-channel Alerts

This n8n workflow enables automated, AI-powered monitoring of multiple websites on a schedule. It fetches website lists from Google Sheets, uses browser-tools-mcp for performance checks and mcp-recon for security reconnaissance, then leverages GPT-4 Mini to analyze results, categorize issues as critical, warning, or info, and generate summaries.

Benefits include real-time detection of downtime, vulnerabilities, or anomalies without manual intervention, reducing monitoring time from hours to minutes. Multi-channel alerts ensure critical issues reach teams instantly via Slack and email, while comprehensive logging in Google Sheets supports trend analysis, reporting, and historical tracking for proactive maintenance.

Ideal for DevOps engineers, website admins, digital agencies, and technical teams in travel & hospitality managing price-sensitive sites or high-traffic platforms. Use cases: monitor travel booking sites for price changes/security, e-commerce for uptime, or corporate sites for compliance. Setup requires MCP servers, OpenAI key, Sheets, Slack, and SMTP configs stored in env vars.
