WHAT IT DOES

What update_scoped_app does on ServiceNow-MCP

AI agents use update_scoped_app 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 update_scoped_app is rated Medium

This tool creates or modifies data reversibly within ServiceNow's application framework. While 'update' is inherently Write-category, the severity is elevated to 'high' because: (1) scoped apps can contain custom code and business logic affecting multiple users/processes; (2) unauthorized app modifications could enable privilege escalation, inject malicious logic, or disrupt critical workflows; (3) ServiceNow scoped…

From the tool's definition Tool name 'update_scoped_app' performs an update operation. Description explicitly states 'Update an existing scoped application' and requires 'WRITE_ENABLED=true', confirming it modifies data.

RECOMMENDED RULE

The rule that runs update_scoped_app safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_scoped_app, this is the rule to start with:

update_scoped_app Rate-limited

update_scoped_app stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
