What create_ui_policy does on NowAIKit — ServiceNow AI Toolkit

AI agents use create_ui_policy 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_ui_policy 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 create_ui_policy, this is the rule to start with:

create_ui_policy Rate-limited

create_ui_policy 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.
