What list_acls does on NowAIKit — ServiceNow AI Toolkit
AI agents call list_acls 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.
Why list_acls is rated Low
This tool retrieves and displays access control configuration data. While the sensitivity is high because ACL data reveals security posture and permission boundaries (useful for reconnaissance or privilege escalation planning), the tool itself performs no modifications, deletions, or code execution. It is purely a query/read operation.
From the tool's definition Tool name 'list_acls' and description 'List Access Control rules' indicate retrieval of data. The description explicitly states the function is to list/query ACLs that define permissions (who can read/write/create/delete records), not to modify or delete them.
Attacks that exploit this kind of access
The rule that runs list_acls 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_acls, this is the rule to start with:
list_acls is read-only, so it stays allowed. 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 list_acls call is checked against it from then on.
Questions about list_acls
List Access Control rules (ACLs) — who can read/write/create/delete records (requires SCRIPTING_ENABLED=true). It is categorised as a Read tool in the NowAIKit — ServiceNow AI Toolkit MCP Server, which means it retrieves data without modifying state.
Register the NowAIKit — ServiceNow AI Toolkit MCP server in PolicyLayer and add a rule for list_acls: 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.
list_acls is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_acls 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 list_acls. 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.
list_acls 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.
