Airflow + Perplexity: Complete MCP Integration

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

When integrated with Perplexity, 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 Perplexity, 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 Perplexity
• 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
• Perplexity installed and configured
• Compatible operating system (macOS App)

Installation

Step 1: Install Airflow

Configuration

Step 2: Configure Perplexity

1. Open Perplexity 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 Perplexity:

Pipeline Monitoring

undefined

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

Expected Result: undefined

Manual DAG Execution

undefined

Ask Perplexity: "Trigger monthly_report DAG with date parameter"

Expected Result: undefined

Troubleshooting Failed Tasks

undefined

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

Expected Result: undefined

Testing Your Setup

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

Troubleshooting

Common Issues

Connector Fails to Start

Symptoms: Status remains "Inactive" or shows error, Red dot indicator

Cause: Command not found or missing dependencies in the environment.

Solution:

• Test the command in a regular terminal window to ensure it works.
• Use absolute paths for all executables (e.g., use /opt/homebrew/bin/node instead of node).
• Check if the server requires specific environment variables.

Permission Errors

Symptoms: "Access denied" responses, Server crashes on file access

Cause: macOS permissions blocking access to specific folders.

Solution:

• Ensure Perplexity (or the terminal running the server) has Full Disk Access in macOS System Settings if accessing sensitive directories.
• Verify PerplexityXPC is correctly installed.

Tools Not Visible

Symptoms: Perplexity does not attempt to use the tool, Hallucinated responses

Cause: Connector not selected as a source.

Solution:

• Start a NEW thread.
• Explicitly select the connector in the "Sources" menu before sending the prompt.

Airflow not appearing in Perplexity

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

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