MCP Servers

mcp-airflow

MCP server exposing Apache Airflow REST API operations as tools — list DAGs, inspect runs and task instances, trigger DAG runs, and check failed DAGs and scheduler health

README

mcp-airflow

MCP server that exposes Apache Airflow REST API operations as tools. Built with FastMCP.

Install

# Run directly with uvx (no install needed)
uvx mcp-airflow

# Or install with pip
pip install mcp-airflow

For development:

uv pip install -e ".[dev]"
# or with dependency groups
uv sync --group dev

Configuration

Set these environment variables (or create a .env file from .env.example):

Variable	Description	Example
`AIRFLOW_BASE_URL`	Airflow REST API base URL. Use `/api/v2` for Airflow 3.x or `/api/v1` for 2.x	`http://100.x.x.x:8080/api/v2`
`AIRFLOW_USERNAME`	Auth username (JWT on 3.x, basic auth on 2.x)	`admin`
`AIRFLOW_PASSWORD`	Auth password

Authentication

The client picks the auth scheme automatically based on your Airflow version:

Airflow 3.x (JWT) — a JWT token is obtained from the /auth/token endpoint using AIRFLOW_USERNAME/AIRFLOW_PASSWORD, sent as a Bearer token, and refreshed automatically. Point AIRFLOW_BASE_URL at /api/v2.
Airflow 2.x (basic auth) — if the JWT flow is unavailable, the client falls back to HTTP basic auth with the same username/password. Point AIRFLOW_BASE_URL at /api/v1.

Usage

Run the server:

mcp-airflow

Or add to your MCP client config (e.g., Claude Desktop):

{
  "mcpServers": {
    "airflow": {
      "command": "mcp-airflow",
      "env": {
        "AIRFLOW_BASE_URL": "http://100.x.x.x:8080/api/v2",
        "AIRFLOW_USERNAME": "admin",
        "AIRFLOW_PASSWORD": "your-password"
      }
    }
  }
}
