WHAT IT DOES

What create_ux_app_route does on ServiceNow-MCP

AI agents use create_ux_app_route to create or update resources in ServiceNow-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ServiceNow-MCP environment.

RISK

Why create_ux_app_route is rated Medium

Creating UX app routes modifies application configuration reversibly. While it doesn't delete data, it could redirect traffic, expose endpoints, or alter application behavior in ways that might be noticed and corrected. Impact is medium because misuse could disrupt application routing and user access, but the action is reversible—routes can be removed or reconfigured.

From the tool's definition Tool creates/registers new routes (URL paths) in a UX app. The description explicitly states "Register a new route" which is a creation action. The tag "[Write]" further confirms this is a write operation.
