WHAT IT DOES

What delete-user-data does on Mcp Dev

AI agents call delete-user-data to permanently remove resources in Mcp Dev, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete-user-data is rated Critical

This tool performs permanent deletion of user data, which cannot be undone. This is a destructive operation with high blast radius—an AI agent with access could maliciously or accidentally erase user accounts or personal information. While not financial in nature, the irreversible data loss and potential privacy/compliance violations (GDPR, etc.) elevate this to critical severity.

From the tool's definition Tool name is 'delete-user-data' and description explicitly states 'Deletes user data by its id'. The verb 'deletes' indicates irreversible removal of data.

RECOMMENDED RULE

The rule that runs delete-user-data safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Dev, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete-user-data, this is the rule to start with:

delete-user-data Hidden

delete-user-data is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
