WHAT IT DOES

What remove_contact_group_members does on TrekMail MCP Server

AI agents call remove_contact_group_members to permanently remove resources in TrekMail MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why remove_contact_group_members is rated Critical

Removing contacts from a group destroys the membership relationship. Unlike soft modifications (update/edit), removal of group members is typically not reversible without manual re-addition, making this Destructive. The blast radius is medium since it affects contact group memberships but not the contacts or group themselves.

From the tool's definition 'Remove one or more contacts from a group' — removal of members from a group is an irreversible operation that deletes the association between contacts and the group.
