airflow-mcp-server: Instructions file for Claude Code

CLAUDE.md

airflow-mcp-server CLAUDE.md is an instructions file for Claude Code from us-all/airflow-mcp-server. It costs 1,177 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that exposes Apache Airflow's web API to coding agents. Airflow is a platform for scheduling and monitoring data workflows; MCP is a standard way to make tools available to an agent.

In plain words
What is it for?
Use them when changing, building, or running this Airflow MCP server, including its tools, API client, configuration, tests, and read-only or write-enabled behavior.
Why use it?
They give the agent the project context, required files, supported Airflow versions, configuration settings, and rules for limiting write operations.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is us-all/airflow-mcp-server's own configuration. It tells Claude Code how to work on airflow-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything airflow-mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

airflow-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

프로젝트 개요

@us-all/airflow-mcp — Airflow Stable REST API를 stdio MCP로 노출. 16 도구 + 2 Prompts. read-only 기본, trigger/clear는 AIRFLOW_ALLOW_WRITE=true 게이트.

  • 타겟: Airflow 3.0–3.2 /api/v2 + JWT (SimpleAuthManager). 3.2.1까지 verified (2026-05 기준). Airflow 2.x basic auth는 v0.1.x로 핀.
  • 표준: @us-all MCP Standard 준수
  • Companion: dbt 자산은 별도 @us-all/dbt-mcp

최근 변경사항

  • v1.4.1 (2026-06-19): MCP tool annotations 적용 — @us-all/mcp-toolkit ^1.3.0inferToolAnnotations를 중앙 tool() 헬퍼에 추가, 전 도구에 readOnlyHint/destructiveHint/openWorldHint 자동 부여 (airflow- prefix는 toolkit이 자동 strip, override 0). 비파괴 패치. PASS build / PASS test.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
