Traverse CMDB CI relationships from a starting configuration item. Supports recursive traversal up (dependencies) or down (dependents). Args: - ci_sys_id (string): sys_id of the starting CI - direction (
AI agents call servicenow_get_ci_relationships to retrieve information from Servicenow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves relationship data from the ServiceNow CMDB without modifying any records. It performs a navigational/traversal operation across existing CI relationships, which is a read-only operation. No side effects or data mutations occur.
From the tool's definition Tool description states 'Traverse CMDB CI relationships from a starting configuration item' and 'Supports recursive traversal up (dependencies) or down (dependents).' The verbs 'traverse' and 'get' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Traverse CMDB CI relationships from a starting configuration item. Supports recursive traversal up (dependencies) or down (dependents). Args: - ci_sys_id (string): sys_id of the starting CI - direction (. It is categorised as a Read tool in the Servicenow MCP Server, which means it retrieves data without modifying state.
Register the Servicenow MCP server in PolicyLayer and add a rule for servicenow_get_ci_relationships: 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. Nothing to install.
servicenow_get_ci_relationships 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 servicenow_get_ci_relationships 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 servicenow_get_ci_relationships. 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.
servicenow_get_ci_relationships is provided by the Servicenow MCP server (kylburns89/servicenow-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
