Delete a user
AI agents call deleteUser to permanently remove resources in Follow Up Boss MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes user data from the Follow Up Boss CRM system. Deletion is irreversible and represents a high-severity operation if invoked inappropriately by an AI agent, potentially causing loss of critical account information and associated CRM records.
From the tool's definition Tool name 'deleteUser' combined with description 'Delete a user' indicates permanent removal of a user account. The verb 'delete' is unambiguously destructive, and user deletion in a CRM context results in irreversible data loss.
