stop_torrent · Transmission MCP: Risk & Policy

WHAT IT DOES

What stop_torrent does on Transmission

AI agents use stop_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 stop_torrent needs a policy

Stopping/pausing a torrent is a reversible write operation. It modifies the torrent's state (from active to paused) but does not delete data or cause irreversible effects. The torrent can be restarted at any time, making this a low-severity write action.

From the tool's definition Stop (pause) a torrent — pausing is reversible; the torrent can be resumed
