- Configuration Variables (Edit Fields (Set)): sets 1 field: config
- Load Website List (Google Sheets): uses Google Sheets
- Check Website Source (If): checks a condition and branches into true / false
- Format Default Websites (Edit Fields (Set)): sets 1 field: url
- Batch Website URLs (Loop Over Items (Split in Batches)): loops over the items in batches
- Website Analysis Agent (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 2 tools (mcp-recon, Browser-Tools-MCP)
- Combine Analysis Results (Merge): merges the data from its input branches
- Alert Severity Router (Switch): routes items into 3 branches
- Critical Slack Alert (Slack): uses Slack
- Critical Email Alert (Send Email): sends an email over SMTP
