Search CMDB configuration items
AI agents call cmdb_search to retrieve information from ServiceNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The CMDB (Configuration Management Database) search function retrieves configuration item data without creating, modifying, or deleting records. It is a read-only operation typical of knowledge retrieval and discovery. While CMDB data may be sensitive, the search itself presents minimal risk when used as intended—it simply queries existing data. The blast radius is limited to information disclosure only.
From the tool's definition Tool name 'cmdb_search' and description 'Search CMDB configuration items' indicate a query/retrieval operation without modification capability.

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