Delete a contact group. Requires TREKMAIL_ALLOW_DESTRUCTIVE=true.
AI agents call delete_contact_group 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.
This tool performs an irreversible deletion operation on contact groups. The explicit requirement for a destructive permission flag confirms the developers classified this as a destructive action. Deletion of contact groups is a high-severity risk because it affects email infrastructure and could disrupt communications for multiple users if the wrong group is deleted by an agent.
From the tool's definition 'Delete a contact group' combined with 'Requires TREKMAIL_ALLOW_DESTRUCTIVE=true' indicates this tool irreversibly removes data. Contact groups cannot be recovered once deleted.
