WHAT IT DOES

What list_acc_policies does on ServiceNow-MCP

AI agents call list_acc_policies to retrieve information from ServiceNow-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_acc_policies is rated Low

This tool retrieves and enumerates existing ACC (Application Change Calendar or similar) policies from ServiceNow. The 'list' operation is a read-only query that returns policy information without creating, modifying, or deleting any data. The blast radius of misuse is minimal—an agent listing policies gains only visibility into configuration, not the ability to alter system state or trigger external actions.

From the tool's definition Tool name 'list_acc_policies' with verb 'list' and description 'List ACC monitoring/check policies' indicates data retrieval with no modification capability.
