offline_download · Netdisk MCP: Risk & Policy

WHAT IT DOES

What offline_download does on Netdisk

AI agents invoke offline_download to trigger actions in Netdisk. 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 offline_download needs a policy

Offline download typically triggers an external operation where the cloud storage service fetches a remote URL/resource and saves it to the user's cloud drive. This is an Execute-category action (triggers external operation with side effects), with Write characteristics as well. Since it initiates an external fetch and storage operation, Execute is the most appropriate category.

From the tool's definition Tool name 'offline_download' on a server described as enabling 'offline download' operations for cloud storage (Quark and 115 drives). The description is empty, lowering confidence.
