Map Workflows ↔ Supabase Tables

An auditing utility that scans all active workflows and builds a map of which Supabase tables each scenario touches (via which node and operation), documenting workflow-to-database dependencies.

At a glance

• Status: Inactive (manual only). Work-in-progress.
• Trigger: Manual ("When clicking 'Test workflow'").
• Runs on: All active workflows in the instance.
• Talks to: n8n internal API only (no external writes).

How it works

1. The n8n node fetches all active workflows.
2. Prepare Scenarios Array filters to workflows containing Supabase nodes and emits scenario_name plus sorted tableId: nodeName | operation connection strings.
3. A counter and loop scaffold iterates scenarios and their nodes to build the per-node table mapping.

Notes

• Work-in-progress dev utility. Several nodes have dangling connections and it produces no persisted output. It was never activated.
