## Why add_to_reminders is rated Medium

The tool creates new data (reminder entries) in the user's macOS Reminders app. This is a Write action because it modifies application state reversibly—reminders can be deleted or edited afterward. Severity is medium because misuse would clutter the Reminders app with unwanted entries but poses no financial risk, data deletion, or arbitrary code execution.

From the tool's own definition: "Tool explicitly performs 'Add' action to macOS Reminders, which creates new reminder entries. This is a reversible write operation that modifies the user's Reminders database."

## Use case

AI agents use add_to_reminders to create or update resources in School MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your School MCP environment.
