What upload_video does on TikVid MCP Server

WHY IT NEEDS A POLICY

Why upload_video needs a policy

This tool creates new user-generated content on the platform, which is reversible (videos can typically be deleted). It does not execute arbitrary code, delete data irreversibly, or commit financial transactions. The 'medium' severity reflects that an agent could spam, impersonate, or create harmful content at scale, but the action itself remains within the bounds of normal platform use and is undoable.

From the tool's definition Tool description states 'Post a video to TikVid' — this creates new content on the platform. The term 'Post' combined with 'upload_video' confirms content creation/modification capability.
