Search system properties by name, value, or description
AI agents call search_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.
This tool retrieves and queries system property data without side effects. It is a read-only operation that matches the Read category definition (retrieves or queries data; no side effects). The severity is low because searching system properties poses minimal risk even if misused by an AI agent, as it only exposes metadata about configuration without enabling changes or destructive actions.
From the tool's definition The tool description states 'Search system properties by name, value, or description' — it performs a search/query operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Search system properties by name, value, or description. 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 search_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.
search_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 search_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 search_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.
search_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.
