WHY IT NEEDS A POLICY

Why start_video_transcription needs a policy

The 'start_' prefix combined with the server's stated purpose of enabling AI assistants to 'perform video processing tasks' indicates this tool initiates FFmpeg jobs. While the description is empty, the pattern matches other job-starting tools on this server that execute media processing operations. Transcription involves spawning FFmpeg processes with parameters that could be manipulated.

From the tool's definition Tool name is 'start_video_transcription' with empty description, but context indicates this is part of an MCP-FFmpeg server offering video processing tasks.
