WHAT IT DOES

What get_portal_widget does on ServiceNow MCP Server

AI agents call get_portal_widget 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_portal_widget is rated Low

This tool retrieves source code of Service Portal widgets. While it is a Read operation (no side effects), the severity is elevated to medium because source code may contain sensitive information such as API keys, authentication logic, business rules, or confidential algorithms that could be weaponized if an AI agent misuses it to exfiltrate or analyze intellectual property or secrets embedded in widget code.

From the tool's definition Tool description states 'Get full source code (HTML, CSS, client/server scripts)' — retrieval-only operation with no modification or deletion.
