resize-video · Mcp Ffmpeg MCP: Risk & Policy

WHAT IT DOES

What resize-video does on Mcp Ffmpeg

AI agents use resize-video to create or update resources in Mcp Ffmpeg — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Ffmpeg environment.

WHY IT NEEDS A POLICY

Why resize-video needs a policy

Resizing a video creates a new output file at different resolutions. This is a Write operation as it produces new/modified data. It does not delete or overwrite the original source, and it does not execute arbitrary code or commands beyond the predefined resize operation. Severity is medium because misuse could produce unwanted files or consume significant disk/CPU resources.

From the tool's definition 'Resize a video to one or more standard resolutions' — modifies/transforms video output, but the original is typically preserved as a new file is created
