WHAT IT DOES

What copy_move_item does on Synology MCP Server

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

WHY IT NEEDS A POLICY

Why copy_move_item needs a policy

copy_move_item performs reversible modifications to file/folder locations and duplications on a NAS filesystem. While not strictly reading-only (Read), it does not permanently delete data (not Destructive) nor execute arbitrary code (not Execute). It creates or modifies data structures reversibly, fitting Write category.

From the tool's definition Tool name 'copy_move_item' combined with sibling destructive operations (delete_item, delete_shared_folder) and file management context (create_folder, extract_archive) on a Synology NAS server indicates data manipulation capability.
