{

## Why m365_create_event is rated Medium

This tool creates new calendar entries, which is a reversible write operation. It modifies user data (calendar) but the action can be undone by deleting the created event. Severity is medium because unauthorized calendar event creation could cause schedule disruption and social engineering attacks, but does not involve financial transactions or irreversible data destruction.

From the tool's own definition: "Tool name 'create_event' and description 'Create a calendar event in your Microsoft 365 / Outlook calendar' indicate creation of new calendar data."

Risk signals: Accepts raw HTML/template content (body)

## Use case

AI agents use m365_create_event to create or update resources in Local, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local environment.
