What create_reminder_list does on AirMCP
AI agents use create_reminder_list to create or update resources in AirMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AirMCP environment.
Why create_reminder_list is rated Medium
This tool creates a new reminder list in Apple Reminders, modifying the user's data structure. It is reversible (lists can be deleted), so it is Write rather than Destructive. The blast radius is medium because an agent could spam or clutter the user's Reminders app with many unwanted lists, but the impact is non-permanent and localized to one application.
From the tool's definition create_reminder_list — the verb "create" and the action of establishing a new reminder list indicate data creation. The description states it creates a new reminder list, which is a reversible write operation.
Attacks that exploit this kind of access
The rule that runs create_reminder_list safely

create_reminder_list stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every create_reminder_list call is checked against it from then on.
