Delete a group. This destroys all associated records including expenses.
AI agents call splitwise_delete_group to permanently remove resources in Splitwise MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently and irreversibly deletes a group and all its associated data (expenses, comments, etc.). This is a destructive operation that cannot be undone. The blast radius is high—an AI agent misusing this could destroy shared financial records affecting multiple people, causing loss of expense history and auditing capability.
From the tool's definition Tool description explicitly states 'Delete a group. This destroys all associated records including expenses.' The verbs 'delete' and 'destroys' combined with 'all associated records' indicate irreversible data destruction.
