Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Set these up before or after installing:
Environment variable: AIRFLOW_API_URL
Environment variable: AIRFLOW_USERNAME
Environment variable: AIRFLOW_PASSWORD
Environment variable: AIRFLOW_ALLOW_WRITE
Environment variable: AIRFLOW_TOOLS
Environment variable: AIRFLOW_DISABLE
Add this to your MCP configuration file:

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.
airflow + meta categoriespnpm add -D @us-all/airflow-mcp
AIRFLOW_API_URL=http://airflow.example.com:8080 \
AIRFLOW_USERNAME=admin AIRFLOW_PASSWORD=... \
npx @us-all/airflow-mcp
Pass the host base only — the server prepends /api/v2 internally. A trailing /api/v1 or /api/v2 is stripped if supplied. JWT tokens are cached for the lifetime of the session and refreshed 1 minute before they expire.
The server speaks MCP stdio; wire it into Claude Desktop / Cursor / any MCP client. Set MCP_TRANSPORT=http to opt in to Streamable HTTP transport (Bearer auth, /health endpoint).
airflow (6 + 1 aggregation)| Tool | Description |
|---|---|
airflow-list-dags | List active DAGs with tag/search filters |
airflow-list-runs | Recent runs of one DAG (state filter, ordered newest first) |
airflow-get-task-instances | Task instances for a specific DAG run |
airflow-get-task-logs | Tail (last N kB) of one task instance log |
airflow-trigger-dag | Trigger a new run (write-gated) |
airflow-clear-task | Clear specific task instances → re-run (write-gated) |
dag-health-rollup | Aggregated DAG health: success rate + avg duration + last failed run + failing tasks |
metasearch-tools — natural-language tool discovery.
| Prompt | Use when |
|---|---|
dag-failure-triage | "Why did DAG X fail?" — pulls runs, isolates failure, dumps logs, proposes remediation |
dag-schedule-audit | "Sweep all DAGs for low success rate and stuck runs" |
| Env | Required | Notes |
|---|---|---|
AIRFLOW_API_URL | yes | Airflow host base, e.g. http://airflow.example.com:8080. Trailing /api/v1 or /api/v2 is stripped if present |
AIRFLOW_USERNAME | yes | Username for JWT minting via SimpleAuthManager /auth/token |
AIRFLOW_PASSWORD | yes | Password for JWT minting (secret) |
AIRFLOW_ALLOW_WRITE | no | true enables airflow-trigger-dag / airflow-clear-task |
AIRFLOW_TOOLS / AIRFLOW_DISABLE | no | Category toggles |
/api/v2 (verified against 3.2.1, current Airflow release as of 2026-05). Airflow 2.x is not supported by v0.2+ because basic auth + /api/v1 were removed; pin to @us-all/airflow-mcp@0.1.0 for Airflow 2.x deployments.For dbt artifact parsing, run-results history, and DQ result tables, install @us-all/dbt-mcp alongside.
