WHAT IT DOES

What supabase_delete_user does on Integrations MCP

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

RISK

Why supabase_delete_user is rated Critical

This tool permanently removes user authentication data from a Supabase project, which cannot be undone and represents loss of a user account. This is a destructive operation with significant blast radius if triggered incorrectly by an AI agent (e.g., deleting the wrong user). While not financial in nature, destructive operations rank above execute/write/read in severity.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete an auth user from the Supabase project' — this is an irreversible removal of user authentication records.
