manage_download · Synology MCP Server MCP: Risk & Policy

WHAT IT DOES

What manage_download does on Synology MCP Server

AI agents invoke manage_download to trigger actions in Synology MCP Server. 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 manage_download needs a policy

The tool controls download tasks by pausing, resuming, or deleting them. While 'delete' could be destructive, the primary function is controlling/managing running tasks (Execute). Since the most severe applicable action here is deleting a download task (not irreversible data loss on the NAS itself, just removing a queued/active download job), Execute is the best fit.

From the tool's definition Pause, resume or delete download tasks. [control]
