## Why mixpanel_track_event is rated Medium

This tool sends/writes event data to Mixpanel analytics. It creates new records in the analytics system. While not destructive or financial, it modifies external state by writing tracking data, and misuse could pollute analytics data or be used for tracking manipulation.

From the tool's own definition: "Track a custom event in Mixpanel"

Risk signals: Handles credentials or secrets (token)
