start_change_resolution · Mcp Ffmpeg MCP: Risk & Policy

WHAT IT DOES

What start_change_resolution does on Mcp Ffmpeg

AI agents invoke start_change_resolution to trigger actions in Mcp Ffmpeg. 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 start_change_resolution needs a policy

This tool executes FFmpeg commands to process video files. While video conversion itself is reversible (Write-like), the tool initiates external processes whose side effects are determined by user-supplied arguments. An AI agent could misuse this to process arbitrary files, consume computational resources, or convert videos in unintended ways.

From the tool's definition Tool name 'start_change_resolution' and sibling tools like 'start_audio_extraction', 'start_trim', 'start_change_format' indicate this initiates FFmpeg operations.
