WHAT IT DOES

What generate_video does on Tavus MCP Server

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

WHY IT NEEDS A POLICY

Why generate_video needs a policy

This tool creates a new video asset using a replica and provided script or audio. It is a Write operation (creates new data/content). The severity is high because it consumes API credits/resources, can generate potentially harmful deepfake-style video content using replicas, and could be misused at scale to produce large amounts of synthetic media.
