RISK

Why create_reminder is rated Medium

This tool creates a new reminder entry in the Reminders application, which is a write operation that adds data to a local system. It is reversible (the reminder can be deleted later) and has minimal blast radius—creating unwanted reminders is inconvenient but not destructive or harmful. No financial, destructive, or code execution aspects are involved.

From the tool's definition Tool name 'create_reminder' and description 'Creates a reminder in Reminders.app' indicate data creation. The action is reversible (reminders can be deleted).

RECOMMENDED RULE

The rule that runs create_reminder safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Local, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_reminder, this is the rule to start with:

create_reminder Rate-limited

create_reminder 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.
