What rollback_changes does on NowAIKit — ServiceNow AI Toolkit
AI agents call rollback_changes to permanently remove resources in NowAIKit — ServiceNow AI Toolkit, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why rollback_changes is rated Critical
An AI agent that decides to call rollback_changes doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from NowAIKit — ServiceNow AI Toolkit is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs rollback_changes safely
PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rollback_changes, this is the rule to start with:
rollback_changes is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every rollback_changes call is checked against it from then on.

It is categorised as a Destructive tool in the NowAIKit — ServiceNow AI Toolkit MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the NowAIKit — ServiceNow AI Toolkit MCP server in PolicyLayer and add a rule for rollback_changes: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NowAIKit — ServiceNow AI Toolkit. Nothing to install.
rollback_changes is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the rollback_changes rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for rollback_changes. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
rollback_changes is provided by the NowAIKit — ServiceNow AI Toolkit MCP server (nowaikit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
