What rollback_deployment does on NowAIKit — ServiceNow AI Toolkit
AI agents call rollback_deployment 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_deployment is rated Critical
Reverting an update set is a destructive, hard-to-undo operation that overwrites or removes previously deployed changes in ServiceNow. While the description self-labels it as '[Write]', rolling back a deployment eliminates applied changes and can break dependent configurations, making it more accurately Destructive. Severity is high due to the potential blast radius on live system configurations.

Attacks that exploit this kind of access
The rule that runs rollback_deployment 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_deployment, this is the rule to start with:
rollback_deployment 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_deployment call is checked against it from then on.
Questions about rollback_deployment
Rollback a deployment by reverting an update set. [Write]. 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_deployment: 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_deployment 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_deployment 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_deployment. 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_deployment 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.
