WHAT IT DOES

What create-task does on Outlook MCP Server

WHY IT NEEDS A POLICY

Why create-task needs a policy

This tool creates new data (a task) in a reversible manner. The operation can be undone by deleting the task. It does not execute arbitrary code, delete data irreversibly, move money, or retrieve existing data. The severity is medium because misuse could create unwanted tasks cluttering the user's task list, but the impact is limited and reversible. This is clearly a Write operation.

From the tool's definition Tool name is 'create-task' and description states it 'Creates a new task in a To Do task list', which is a create operation that adds new data to the user's task management system.
