move_torrent · Transmission MCP: Risk & Policy

WHAT IT DOES

What move_torrent does on Transmission

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

WHY IT NEEDS A POLICY

Why move_torrent needs a policy

Moving torrent data modifies the state of the system by relocating files to a new directory, which is a reversible Write operation. While the operation changes data location, it does not permanently delete data (Destructive) or execute arbitrary code (Execute). The severity is medium because a misguided move could cause disk space issues or temporary service disruption, but the operation is reversible.

From the tool's definition Tool name 'move_torrent' and description 'Move torrent data to a new location' indicates modification of file/data location without deletion.
