Airflow + Postman: Complete MCP Integration

Airflow is a MCP server that A MCP Server that connects to Apache Airflow using official python client..

When integrated with Postman, you can:

• List all available DAGs in Airflow
• Manually trigger a DAG run
• Get DAG run history and status

This guide provides step-by-step instructions to set up Airflow in Postman, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

• Airflow will be fully integrated and operational
• You can use Airflow tools directly in Postman
• All Airflow capabilities will be available for your workflows
• Access to 5 different tools

Prerequisites

Before starting, ensure you have:

• Airflow webserver host URL
• Airflow authentication username
• Airflow authentication password
• Postman installed and configured
• Compatible operating system (Desktop App, Web)

Installation

Step 1: Install Airflow

Configuration

Step 2: Configure Postman

1. Open Postman settings
2. Navigate to MCP server configuration
3. Add Airflow server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use Airflow in Postman:

Pipeline Monitoring

undefined

Ask Postman: "Check status of all DAGs and recent failures"

Expected Result: undefined

Manual DAG Execution

undefined

Ask Postman: "Trigger monthly_report DAG with date parameter"

Expected Result: undefined

Troubleshooting Failed Tasks

undefined

Ask Postman: "Show failed tasks in data_pipeline and their error logs"

Expected Result: undefined

Testing Your Setup

1. Launch Postman
2. Verify Airflow is available in the tools list
3. Test basic Airflow functionality

Troubleshooting

Common Issues

Stdio Connection Failed

Symptoms: Process exited immediately, Command not found

Cause: Path issues or missing dependencies (node/python/uv)

Solution:

• Use absolute paths for executables
• Ensure the command runs in a standard terminal
• Check Environment Variables in Postman settings

SSE Connection Error

Symptoms: Connection refused, 404 Not Found

Cause: Server not running or incorrect URL

Solution:

• Verify the MCP server is listening on the correct port
• Check if the server requires headers/auth (add them in Postman)

Airflow not appearing in Postman

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Airflow installation
• Restart Postman
• Check logs for error messages
