📝 Step-by-Step Guide

Step 1: Connect Database Sources

Configure the PostgreSQL MCP server with read-only credentials to your source database. This allows the AI agent to query tables, inspect schemas, and understand data relationships without risk of accidental modifications.

Step 2: Define Transformation Rules

Describe your transformation requirements in natural language: 'Aggregate daily sales by region, calculate 7-day moving averages, flag anomalies beyond 2 standard deviations.' The AI agent translates these into SQL queries.

Step 3: Build the ETL Flow in n8n

Create an n8n workflow with scheduled triggers. The AI agent node receives the transformation description, generates appropriate SQL, executes via MCP, and pipes results to the next step. Use n8n's error handling for retry logic.

Step 4: Set Up Data Validation

Add validation steps: row count checks, null value thresholds, data type verification, and referential integrity tests. The AI agent can dynamically generate validation queries based on the data schema.

Step 5: Configure Output and Alerts

Route processed data to your destination: a data warehouse, CSV export via Filesystem MCP, or a dashboard API. Set up Slack notifications for pipeline failures or data quality alerts.

💡 Use Cases

  • Data teams automating recurring ETL jobs
