Setup

Usage with Claude Desktop

Stdio Transport (Default)

{
    "mcpServers": {
        "airflow-mcp-server": {
            "command": "uvx",
            "args": [
                "airflow-mcp-server",
                "--base-url",
                "http://localhost:8080",
                "--auth-token",
                "<jwt_token>"
            ]
        }
    }
}

See CONFIG.md for IDE-specific configuration examples across popular MCP clients.

HTTP Transport

{
    "mcpServers": {
        "airflow-mcp-server-http": {
            "command": "uvx",
            "args": [
                "airflow-mcp-server",
                "--http",
                "--port",
                "3000",
                "--base-url",
                "http://localhost:8080",
                "--auth-token",
                "<jwt_token>"
            ]
        }
    }
}

Note:

• Set base_url to the root Airflow URL (e.g., http://localhost:8080).
• Do not include /api/v2 in the base URL. The server will automatically fetch the OpenAPI spec from ${base_url}/openapi.json.
• Only JWT token is required for authentication. Cookie and basic auth are no longer supported in Airflow 3.0.

Transport Options

The server supports multiple transport protocols:

Stdio Transport (Default)

Standard input/output transport for direct process communication:

airflow-mcp-server --safe --base-url http://localhost:8080 --auth-token <jwt>

HTTP Transport

Uses Streamable HTTP for better scalability and web compatibility:

airflow-mcp-server --safe --http --port 3000 --base-url http://localhost:8080 --auth-token <jwt>

Note: SSE transport is deprecated. Use --http for new deployments as it provides better bidirectional communication and is the recommended approach by FastMCP.

Operation Modes

The server supports two operation modes:

• Safe Mode (--safe): Only allows read-only operations (GET requests). This is useful when you want to prevent any modifications to your Airflow instance.
• Unsafe Mode (--unsafe): Allows all operations including modifications. This is the default mode.

To start in safe mode:

airflow-mcp-server --safe

To explicitly start in unsafe mode (though this is default):

airflow-mcp-server --unsafe

Tool Discovery Modes

The server supports two tool discovery approaches:

• Hierarchical Discovery (default): Tools are organized by categories (DAGs, Tasks, Connections, etc.). Browse categories first, then select specific tools. More manageable for large APIs.
• Static Tools (--static-tools): All tools available immediately. Better for programmatic access but can be overwhelming.

To use static tools:

airflow-mcp-server --static-tools

Command Line Options

Usage: airflow-mcp-server [OPTIONS]

  MCP server for Airflow

Options:
  -v, --verbose      Increase verbosity
  -s, --safe         Use only read-only tools
  -u, --unsafe       Use all tools (default)
  --static-tools     Use static tools instead of hierarchical discovery
  --base-url TEXT    Airflow API base URL
  --auth-token TEXT  Authentication token (JWT)
  --http             Use HTTP (Streamable HTTP) transport instead of stdio
  --sse              Use Server-Sent Events transport (deprecated, use --http
                     instead)
  --port INTEGER     Port to run HTTP/SSE server on (default: 3000)
  --host TEXT        Host to bind HTTP/SSE server to (default: localhost)
  --help             Show this message and exit.

Using Resources

Point the server at a folder of Markdown guides whenever you want agents to reference local documentation:

airflow-mcp-server --base-url http://localhost:8080 --auth-token <jwt> --resources-dir ~/airflow-resources

• Every top-level .md/.markdown file becomes a read-only resource (file:///<slug>) visible in your MCP client.
• The first # Heading in each file (if present) is used as the resource title; otherwise the filename stem is used.
• Set AIRFLOW_MCP_RESOURCES_DIR=/path/to/docs if you prefer environment-based configuration.
• Update the files on disk and restart the server to refresh the resources list.

Considerations

Authentication

• Only JWT authentication is supported in Airflow 3.0. You must provide a valid AUTH_TOKEN.

Page Limit

The default is 100 items, but you can change it using maximum_page_limit option in [api] section in the airflow.cfg file.

Transport Selection

• Use stdio transport for direct process communication (default)
• Use HTTP transport for web deployments, multiple clients, or when you need better scalability
• Avoid SSE transport as it's deprecated in favor of HTTP transport
