WHAT IT DOES

What generate_video does on DemoStudio

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

RISK

Why generate_video is rated Medium

This tool creates a new video asset based on a text prompt. It is a Write operation (content creation) with no indication of code execution, financial transactions, or irreversible deletion. The blast radius is medium because an AI agent could generate large volumes of video content or inappropriate material, but effects are reversible (videos can be deleted).

From the tool's definition "Generate a short-form demo video" from a text prompt — creates new media content

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs generate_video safely

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

generate_video Rate-limited

generate_video 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.
