quit_group · RongCloud MCP Server MCP: Risk & Policy

WHAT IT DOES

What quit_group does on RongCloud MCP Server

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

WHY IT NEEDS A POLICY

Why quit_group needs a policy

Removing users from a group chat is a reversible write operation — users can be re-added. It modifies group membership state but does not permanently delete data or the group itself. The blast radius is medium since an AI agent could erroneously remove legitimate members from group conversations.
