WHAT IT DOES

What list_subflows does on NowAIKit — ServiceNow AI Toolkit

AI agents call list_subflows to retrieve information from NowAIKit — ServiceNow AI Toolkit without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_subflows is rated Low

This tool retrieves metadata about available subflows in the ServiceNow system. It performs a query-like operation with no side effects—no data is created, modified, deleted, or executed. The blast radius if misused by an AI agent is minimal, as it only exposes information about what subflows exist, not their execution or modification.

From the tool's definition Tool name 'list_subflows' and description 'List available subflows that can be reused across flows' indicate a retrieval operation that queries and returns information about available subflows without modifying any data.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_subflows Allowed

list_subflows is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_subflows": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every list_subflows call is checked against it from then on.

Can I rate-limit list_subflows? +

Yes. Add a rate_limit block to the list_subflows 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.

How do I block list_subflows completely? +

Set action: deny in the PolicyLayer policy for list_subflows. 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.
