What get_acl does on NowAIKit — ServiceNow AI Toolkit
AI agents call get_acl 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 get_acl is rated Low
This is fundamentally a Read operation as it queries and returns data about ACL rules without modifying them. However, severity is elevated to 'high' because: (1) ACL rules control access to ServiceNow resources across the system, (2) script contents may contain sensitive business logic or credentials, (3) role requirements expose authorization structure, and (4) the SCRIPTING_ENABLED=true requirement suggests…
From the tool's definition Tool retrieves and returns 'full details of an ACL rule including its script and role requirements' — a read/retrieval operation with no modification capability.
Attacks that exploit this kind of access
The rule that runs get_acl 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 get_acl, this is the rule to start with:
get_acl 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 get_acl call is checked against it from then on.
Questions about get_acl
Get full details of an ACL rule including its script and role requirements (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 get_acl: 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.
get_acl 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 get_acl 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 get_acl. 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.
get_acl 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.
