WHAT IT DOES

What update_scoped_app does on NowAIKit — ServiceNow AI Toolkit

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

RISK

Why update_scoped_app is rated Medium

This tool modifies existing scoped applications in ServiceNow, which are potentially critical system components. Unauthorized updates could alter application behavior, permissions, or dependencies, affecting multiple users and workflows. However, it is reversible (can be undone by another update), so it is classified as Write rather than Destructive.

From the tool's definition Tool name 'update_scoped_app' and description 'Update an existing scoped application' indicate modification of application configuration/metadata. The requirement flag 'WRITE_ENABLED=true' confirms this is a write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_scoped_app safely

PolicyLayer is an MCP gateway: it sits between your AI agents and NowAIKit — ServiceNow AI Toolkit, 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.
