verify_torrent · Transmission MCP: Risk & Policy

WHAT IT DOES

What verify_torrent does on Transmission

AI agents invoke verify_torrent to trigger actions in Transmission. 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 verify_torrent needs a policy

Verifying torrent data integrity initiates an active scan/re-hash of all torrent file data on disk. This is not a simple read (it triggers a background process in Transmission), not destructive or financial, but it does execute an operation with side effects (CPU/disk I/O load, potential state changes in the torrent client). Misuse could cause significant disk I/O or interfere with ongoing downloads.

From the tool's definition 'Verify torrent data integrity' — triggers an active verification/hash-check operation on torrent data

verify_torrent Rate-limited

verify_torrent stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
