What delete_system_property does on NowAIKit — ServiceNow AI Toolkit
AI agents call delete_system_property 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 delete_system_property is rated Critical
Deletion of system properties cannot be undone and permanently removes configuration data that may be critical to system operation. While labeled '[Write]' in the description, the actual function—delete—is destructive in nature. The blast radius is high: misconfigured or malicious deletion of system properties could break application functionality, workflows, or integrations across the entire ServiceNow instance.
From the tool's definition delete_system_property deletes a system property by name; the operation is irreversible and explicitly removes data from the ServiceNow system.
Attacks that exploit this kind of access
The rule that runs delete_system_property 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 delete_system_property, this is the rule to start with:
delete_system_property 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 delete_system_property call is checked against it from then on.
