List system properties with optional filtering
AI agents call list_system_properties 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.
The verb 'list' combined with 'optional filtering' clearly describes a data retrieval operation. This tool queries and returns existing system properties without creating, modifying, deleting, or executing anything. The blast radius is minimal since it only exposes information already within the ServiceNow instance. No side effects or state changes are implied.
From the tool's definition Tool name 'list_system_properties' and description 'List system properties with optional filtering' indicate a read-only query operation that retrieves system configuration data without modification.
Attacks that exploit this kind of access
List system properties with optional filtering. It is categorised as a Read tool in the ServiceNow-MCP MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_system_properties: 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_system_properties 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_system_properties 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_system_properties. 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_system_properties 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.
