Airflow

us-all/airflow-mcp-server

Wraps the Airflow 3.x REST API with read-heavy defaults and optional write operations behind an env flag. You get seven tools to list DAGs, pull runs and task instances, tail logs, and trigger or clear tasks when AIRFLOW_ALLOW_WRITE is true. Auth is handled via SimpleAuthManager JWT that the server mints and refreshes transparently from username and password. Ships with two prompts for failure triage and schedule audits, plus a dag-health-rollup aggregation that replaces the usual list-then-fetch dance. Reach for this when you're debugging pipelines in Claude and want to skip the Airflow UI. Airflow 2.x is not supported; the server expects /api/v2 and the auth changes that shipped in 3.0.

Readme

@us-all/airflow-mcp

Airflow MCP server — read DAGs, runs, task instances, log tails; trigger and clear (write-gated). Built on @us-all/mcp-toolkit.

A focused MCP for the Airflow 3.x REST API (/api/v2). Read by default; airflow-trigger-dag and airflow-clear-task are gated behind AIRFLOW_ALLOW_WRITE=true. Auth is JWT via SimpleAuthManager — supply AIRFLOW_USERNAME + AIRFLOW_PASSWORD and the server mints/refreshes the token transparently.

For deeper dbt integration (manifest parsing, run-results history, source freshness, per-column test coverage, lineage walks, custom DQ result tables), install the companion @us-all/dbt-mcp alongside.

7 tools in airflow + meta categories
2 MCP Prompts for DAG triage workflows
1 aggregation tool that replaces the list-runs → get-task-instances combo
