create_cli_token · MWAA MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_cli_token does on MWAA MCP Server

AI agents invoke create_cli_token to trigger actions in MWAA MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why create_cli_token needs a policy

A CLI token enables execution of arbitrary Airflow CLI commands, which can trigger DAG runs, modify configurations, manage connections/variables, and perform other operations. The token itself is a credential enabler for Execute-level actions.
