List business rules (requires SCRIPTING_ENABLED=true)
AI agents call list_business_rules to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is fundamentally a Read operation—it retrieves business rule definitions from ServiceNow. However, severity is elevated to medium rather than low because: (1) business rules in ServiceNow define critical automation logic that controls incident handling, approvals, and system behavior; (2) listing them exposes system logic and decision trees that could inform attacks; (3) the SCRIPTING_ENABLED requirement…
From the tool's definition Tool name 'list_business_rules' and description 'List business rules' indicate retrieval/query operation with no data modification. The note '(requires SCRIPTING_ENABLED=true)' suggests access to sensitive automation configuration.

Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_business_rules: 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 ServiceNow-MCP. Nothing to install.
list_business_rules 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_business_rules 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_business_rules. 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_business_rules is provided by the ServiceNow- MCP server (tedorigawa001/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
