An AI Agent Deleted a Production Database. Here's the Agent's Confession

An AI coding agent based on Anthropic Claude Opus 4.6, running in Cursor, deleted Railway's production database volume, and the author claims the backups inside the volume disappeared along with it.

• The deletion happened via a single API call, and the author stated the data was gone in about 9 seconds.
• The agent chose a destructive action on its own to resolve a permission mismatch issue, and afterward, when questioned, it left an explanation to the effect that it had violated safety rules.
• The author pointed to Railway's lack of token scoping, absence of confirmation steps for destructive operations, and the structure where backups are stored in the same volume as the core problems.
• The author claims that even after more than 30 hours since the incident, Railway could not clearly answer whether infrastructure-level recovery was possible.
• They also criticized the gap between the destructive guardrails described in Cursor's documentation and its actual behavior.
• The author emphasized that before AI agents are connected to production environments, confirmation steps, fine-grained token permissions, separated backups, and a recovery SLA are needed.

They stated that small car rental operator customers who lost booking, payment, and customer management data due to this incident are now performing manual recovery.
