WHAT IT DOES

What bulk_complete does on MCP Apple Reminders

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

WHY IT NEEDS A POLICY

Why bulk_complete needs a policy

Bulk-completing reminders modifies reminder state (completeness status) in a reversible manner. This is Write category rather than Destructive because completion status can be undone (reminders can be marked incomplete). Severity is medium because bulk operations could affect many reminders at once, causing confusion or lost task tracking, but the effect is reversible.

From the tool's definition Tool name 'bulk_complete' combined with server context showing 'create, read, update, delete' capabilities and sibling tool 'bulk_delete_completed' indicates this marks multiple reminders as complete, which is a reversible state change to reminder data.
