Version: 1.0.0
n8n Version: 1.88.0+
Author: Koresolucoes License: MIT


Description

A stateful AI agent workflow powered by Supabase and Retrieval-Augmented Generation (RAG). Enables persistent memory, dynamic CRUD operations, and multi-tenant data isolation for AI-driven applications like customer support, task orchestration, and knowledge management.

Key Features:

  • 🧠 RAG Integration: Leverages OpenAI embeddings and Supabase vector search for context-aware responses.
  • 🗃️ Full CRUD: Manage agent_messages, agent_tasks, agent_status, and agent_knowledge in real time.
  • 📤 Multi-Tenant Ready: Supports per-user/organization data isolation via dynamic table names and webhooks.
  • 🔒 Secure: Role-based access control via Supabase Row Level Security (RLS).

Use Cases

  1. Customer Support Chatbots: Persist conversation history and resolve queries using institutional knowledge.
  2. Automated Task Management: Track and update task statuses dynamically.
  3. Knowledge Repositories: Store and retrieve domain-specific information for AI agents.

Instructions

1. Import Template

  • Go to n8n > Templates > Import from File and upload this workflow.

2. Configure Credentials

  • Add your Supabase and OpenAI API keys under Settings > Credentials.

3. Set Up Multi-Tenancy (Optional)

  • Dynamic Webhook Path:
    Replace the default webhook path with /mcp/tool/supabase/:userId to enable per-user routing.
  • Table Names:
    Use a Set Node to dynamically generate table names (e.g., agent_messages_{{userId}}).

4. Activate & Test

  • Enable the workflow and send test requests to the webhook URL.
