WHAT IT DOES

What set_member_card does on Xadeus-QQ-MCP

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

WHY IT NEEDS A POLICY

Why set_member_card needs a policy

This is a Write operation because it creates or modifies data (a member's group nickname) in a reversible manner. The tool can update the card and the change can be undone by setting it again or clearing it. It is not Execute (no code/command execution), not Destructive (fully reversible), not Financial, and not Read (modifies rather than retrieves).

From the tool's definition Tool description states 'Set a member's group nickname (card). Empty string clears it.' This modifies a user-facing attribute (group nickname/card) that can be changed by the tool but is reversible (can be updated or cleared again).
