Summary
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.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

@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+metacategories - 2 MCP Prompts for DAG triage workflows
- 1 aggregation tool that replaces the list-runs → get-task-instances combo
Install
pnpm add -D @us-all/airflow-mcp
Run
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).
Tools
airflow (6 + 1 aggregation)
| Tool | Description |
|---|---|
airflow-list-dags | List active DAGs with tag/search filters |

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 |
meta
search-tools — natural-language tool discovery.
Prompts
| 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" |
Environment variables
| 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 |
Tested-against schemas
- Airflow 3.0–3.2
/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/v1were removed; pin to@us-all/airflow-mcp@0.1.0for Airflow 2.x deployments.
Companion server
For dbt artifact parsing, run-results history, and DQ result tables, install @us-all/dbt-mcp alongside.
Build
pnpm install
pnpm run build # tsc → dist/
pnpm test # vitest
pnpm run smoke # spawns dist/index.js, calls initialize + tools/list (set env first)
