WHAT IT DOES

What get_system_property does on ServiceNow MCP Server

AI agents call get_system_property 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 get_system_property is rated Low

This tool retrieves system properties and their metadata—a read-only query operation with no side effects. The action is data retrieval only. Severity is low as system properties are typically configuration data; blast radius is limited unless properties contain highly sensitive credentials, but ServiceNow systems typically protect such values separately.

From the tool's definition Tool name 'get_system_property' and description 'Get a ServiceNow system property value and metadata by name' indicate retrieval of configuration/property data without modification or execution.
