What is MCP-Server-for-Airflow AGENTS.md?

Repository instructions for an MCP interface to Apache Airflow, a system that schedules and runs data workflows. The project offers a separate server and an Airflow webserver plugin for exposing Airflow operations as agent tools.

Use them when developing the Airflow MCP server or plugin, configuring safe or unsafe modes, selecting transport options, and deciding how the tools should connect to Airflow.

They explain which delivery option fits a deployment: a separate service for richer or multi-tenant workflows, or an in-process plugin for an existing Airflow installation. This helps contributors navigate the two-part project.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01369	$0.01369
Opus 5	$0.00685	$0.00685

Security

Grade A, and why

MCP-Server-for-Airflow AGENTS.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 5d 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.

Origin

This is a copy

Airflow MCP — Agent Ramp-up Guide

Mission

The repo ships two complementary MCP deliverables that sit in front of the Airflow 3 REST API:

airflow-mcp-server – an advanced FastMCP deployment with hierarchical discovery, safe/unsafe modes, transport flexibility, and future prompt/resource hooks.
airflow-mcp-plugin – a lightweight Airflow webserver plugin that simply exposes the Airflow instance’s REST API as MCP tools at /mcp.

Both surfaces expose Airflow operations as MCP tools, but choose based on runtime model:

Server runs as a separate process alongside Airflow and is suited for richer agent workflows or multi-tenant orchestration.
Plugin runs in-process with Airflow and is the easiest path to add MCP access to an existing Airflow deployment without managing another service.

High-level Architecture

airflow-mcp-server (CLI app)

CLI entrypoint: src/airflow_mcp_server/__init__.py exposes Click flags to select safe/unsafe mode, static vs hierarchical tooling, and transport (stdio, streamable-http, sse). It validates configuration via AirflowConfig and dispatches to the async serve_safe or serve_unsafe runners.
Configuration: AirflowConfig (config.py) requires both base_url and auth_token (JWT). CLI flags may be overridden by AIRFLOW_BASE_URL and AUTH_TOKEN environment variables.
Server runners: server_safe.py (GET-only) and server_unsafe.py (all methods) fetch the Airflow OpenAPI spec once at startup, build an httpx.AsyncClient with the caller’s JWT, attach resources/prompts placeholders, and run FastMCP on the selected transport.
Tool generation:
- Static mode: FastMCP autogenerates one tool per OpenAPI operation via FastMCP.from_openapi.
- Hierarchical mode: HierarchicalToolManager groups operations by OpenAPI tag (“category”), keeps navigation tools (browse_categories, select_category, get_current_category), and mounts category-specific FastMCP sub-servers. Utilities live in utils/category_mapper.py.

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.
