RISK

Why complete_reminder is rated Medium

The tool performs a state modification on existing data (marking a reminder as complete), which constitutes a Write operation. It is reversible and has a localized scope (affects only one reminder), making it medium severity. The requirement for confirm=true demonstrates awareness of potential misuse.

From the tool's definition Tool description states it "Marks a reminder complete in Apple Reminders", which modifies the state of an existing reminder from incomplete to complete. This is a reversible change (the reminder can be marked incomplete again).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs complete_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 complete_reminder, this is the rule to start with:

complete_reminder Rate-limited

complete_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.
