WHAT IT DOES

What tool_extend_video does on Open Google Image Generator MCP

AI agents invoke tool_extend_video to trigger actions in Open Google Image Generator MCP. 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 tool_extend_video needs a policy

This tool triggers an external AI generation operation (via Google Cloud Vertex AI) to extend a video, producing new content appended to an existing asset. It is not purely a read operation, and while it modifies/creates content, it runs an external compute/generation process whose effects depend on the input arguments, placing it in the Execute category.
