WHAT IT DOES

What gemini-video-generate does on Gemini MCP Server

AI agents invoke gemini-video-generate to trigger actions in Gemini MCP Server. 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 gemini-video-generate needs a policy

This tool initiates an external media generation operation (video creation) via Google's Veo 3.1 API. It is an Execute-category action because it triggers a substantial external operation whose effects depend on the input arguments. It is not purely Write (local data creation) as it invokes a third-party generative AI pipeline.
