Kick member from group
AI agents call set_group_kick to permanently remove resources in NapCat MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Kicking a group member is a destructive social/platform action: the removal is immediate and cannot be automatically undone. The ejected user loses group membership and access. This has a high blast radius if misused, as an AI agent could mass-kick members from a group.
From the tool's definition 'Kick member from group' — removing a member from a group is an irreversible action (the member is ejected and must be re-invited to rejoin).
