WHAT IT DOES

What app_rollback does on Nasbridge

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

RISK

Why app_rollback is rated Critical

The description explicitly labels this a DESTRUCTIVE operation. Rolling back an application to a previous version overwrites the current state irreversibly (the current version/state is lost), making it a destructive action with high blast radius as it can break running services.

From the tool's definition Rollback an app to a previous version. This is a DESTRUCTIVE operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs app_rollback safely

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

app_rollback Hidden

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