WHAT IT DOES

What list_client_scripts does on ServiceNow MCP Server

AI agents call list_client_scripts 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_client_scripts is rated Low

This tool retrieves or enumerates client scripts from ServiceNow without modifying them. While it has medium severity due to potential information disclosure (scripts may contain sensitive logic, credentials, or business rules), it is fundamentally a Read operation. The requirement flag SCRIPTING_ENABLED=true suggests privileged access, elevating severity from low to medium.

From the tool's definition Tool name 'list_client_scripts' with description 'List client scripts' indicates retrieval/querying of client-side scripts. The 'list' verb and absence of modification keywords (create, update, delete) confirm read-only behavior.
