WHAT IT DOES

What create_flow does on NowAIKit — ServiceNow AI Toolkit

AI agents use create_flow 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 create_flow is rated Medium

This tool creates new Flow Designer flows, which are automation workflows in ServiceNow. While reversible (flows can be deleted), creating flows can establish automated processes that affect business operations, user workflows, and data handling.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_flow Rate-limited

create_flow 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.
