WHAT IT DOES

What list_ui_policies does on ServiceNow MCP Server

AI agents call list_ui_policies to retrieve information from ServiceNow MCP Server 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_ui_policies is rated Low

This tool retrieves existing UI policy configurations (field visibility, mandatory, read-only rules) from ServiceNow. While it does not write or delete data, the medium severity reflects the risk that exposed UI policy details could reveal sensitive business logic about field constraints and visibility rules that might be exploited to understand system vulnerabilities or bypass intended user restrictions.

From the tool's definition Tool name is 'list_ui_policies' and description states 'List UI Policies for a table' — this is a retrieval operation that queries and returns UI policy configurations without modifying them.
