Airflow + mcphub.nvim: Complete MCP Integration

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

When integrated with mcphub.nvim, 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 mcphub.nvim, including configuration, examples, and troubleshooting.

Once configured, you can use Airflow in mcphub.nvim:

Pipeline Monitoring

undefined

Ask mcphub.nvim: "Check status of all DAGs and recent failures"

Expected Result: undefined

Manual DAG Execution

undefined

Ask mcphub.nvim: "Trigger monthly_report DAG with date parameter"

Expected Result: undefined

Troubleshooting Failed Tasks

undefined

Ask mcphub.nvim: "Show failed tasks in data_pipeline and their error logs"

Expected Result: undefined

Testing Your Setup

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

Troubleshooting

Common Issues

Servers not showing in :McpHub

Symptoms: Empty server list, Configuration not loaded

Cause: Incorrect configuration file path or JSON syntax error

Solution:

• Verify servers.json exists in ~/.config/mcphub/ or .vscode/mcp.json in project root
• Check JSON syntax for errors (trailing commas, missing quotes)
• Run :checkhealth mcphub to diagnose issues

Tool execution fails

Symptoms: Error message when AI tries to use tool, No response

Cause: Server command failed or environment variables missing

Solution:

• Check server logs in :McpHub
• Verify "command" path is correct and executable
• Ensure required environment variables are set in the config

Chat plugin not recognizing tools

Symptoms: AI says it cannot perform the action, Tools not listed in chat

Cause: Integration issue with the specific chat plugin

Solution:

• Ensure you are using a supported version of the chat plugin
• Check mcphub.nvim documentation for plugin-specific setup instructions
• Restart Neovim to reload the integration

Airflow not appearing in mcphub.nvim

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Airflow installation
• Restart mcphub.nvim
• Check logs for error messages
