move_resource · Xiaoya Teacher MCP: Risk & Policy

WHAT IT DOES

What move_resource does on Xiaoya Teacher

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

WHY IT NEEDS A POLICY

Why move_resource needs a policy

Moving a resource is a reversible Write operation—it changes where/how a resource is organized or stored without permanent deletion or code execution. The empty description lowers confidence slightly, but context from sibling tools (resource management focus) and the operation's inherent reversibility justify Write classification rather than Execute or Destructive.

From the tool's definition Tool name 'move_resource' suggests relocation/reorganization of educational resources. Sibling tools like 'batch_update_resource_visibility' and 'batch_update_resource_download' confirm this server manages resource state.
