## Why save_tags is rated Medium

This tool creates or modifies tag data associated with videos, which is a Write operation. It does not delete data (not Destructive), does not execute external code or commands (not Execute), does not move money (not Financial), and has side effects beyond just reading (not Read).

From the tool's own definition: "The tool name 'save_tags' and description 'Save classification tags for a video' indicate it modifies metadata associated with a video by writing tags to the knowledge base. This is a reversible write operation on structured data (tags/classifications)."

## Use case

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