WHAT IT DOES

What save_tags does on Mcptube Vision

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.

RISK

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 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).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs save_tags safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcptube Vision, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For save_tags, this is the rule to start with:

save_tags Rate-limited

save_tags stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
