View service dependencies and related CIs for impact analysis
AI agents call service_mapping_summary 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 displays existing service dependency and configuration item (CI) data from ServiceNow's CMDB for informational purposes. It performs passive data retrieval for impact analysis without creating, modifying, executing, or deleting any resources. The blast radius of misuse is limited to potential information disclosure.
From the tool's definition Tool name 'service_mapping_summary' combined with description 'View service dependencies and related CIs for impact analysis' indicates a query/retrieval operation.

Register the ServiceNow- MCP server in PolicyLayer and add a rule for service_mapping_summary: 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.
service_mapping_summary 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 service_mapping_summary 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 service_mapping_summary. 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.
service_mapping_summary 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.
