What create_script_include does on NowAIKit — ServiceNow AI Toolkit
AI agents use create_script_include 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.
Why create_script_include is rated Medium
This tool creates new script objects that can execute arbitrary code within ServiceNow. While script creation is reversible (scripts can be deleted), the ability to inject executable code represents a Write operation with high severity due to potential for abuse—an AI agent could create malicious scripts that execute on the ServiceNow platform.
From the tool's definition Tool name: 'create_script_include'; description: 'Create a new script (requires SCRIPTING_ENABLED=true)'. The tool creates and stores new executable script objects in ServiceNow, which are reversible but grant persistent execution capabilities.
Attacks that exploit this kind of access
The rule that runs create_script_include 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_script_include, this is the rule to start with:
create_script_include 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.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every create_script_include call is checked against it from then on.
Questions about create_script_include
Create a new script include (requires SCRIPTING_ENABLED=true). It is categorised as a Write tool in the NowAIKit — ServiceNow AI Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the NowAIKit — ServiceNow AI Toolkit MCP server in PolicyLayer and add a rule for create_script_include: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NowAIKit — ServiceNow AI Toolkit. Nothing to install.
create_script_include is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_script_include rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_script_include. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_script_include is provided by the NowAIKit — ServiceNow AI Toolkit MCP server (nowaikit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
