WHAT IT DOES

What list_groups does on NowAIKit — ServiceNow AI Toolkit

AI agents call list_groups 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

From the tool's definition Tool name 'list_groups' and description 'List groups with optional search filter' indicate a retrieval operation that returns group information without modifying any data.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_groups Allowed

list_groups 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_groups": {}
  }
}

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_groups call is checked against it from then on.
