Delete a system property by name. [Write]
AI agents call delete_system_property to permanently remove resources in ServiceNow-MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Despite the tool's description label claiming '[Write]', the actual operation is deletion—an irreversible action that destroys data/configuration. System properties are critical infrastructure configuration elements in ServiceNow. Unauthorized or accidental deletion could disrupt service functionality, require manual restoration, and impact multiple dependent processes.
From the tool's definition Tool name 'delete_system_property' and description 'Delete a system property by name' explicitly performs deletion of system configuration properties, which cannot be reversed without administrative restoration.

delete_system_property 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 delete_system_property 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.
