openart_generate_video · Openart MCP: Risk & Policy

WHAT IT DOES

What openart_generate_video does on Openart

AI agents invoke openart_generate_video to trigger actions in Openart. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why openart_generate_video needs a policy

This tool initiates an external computational process (video generation/rendering) on a third-party platform. It is not a simple write/create of a data record but rather triggers a potentially long-running, resource-intensive operation. Misuse could result in excessive API usage, cost accumulation, or generation of inappropriate content at scale.

From the tool's definition 'Generate a video using an existing OpenArt character speaking a script' — triggers an external video rendering operation on OpenArt.ai whose effects (resource consumption, API calls, generated media) depend on arguments passed.
