Search for configuration items (CIs) in the CMDB
AI agents call search_cmdb_ci 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 configuration item data from the Configuration Management Database without creating, modifying, deleting, or executing any operations. It is a read-only query function with minimal risk of misuse by an AI agent. The blast radius is limited to potential information disclosure of CMDB contents, which is typically low-sensitivity metadata.
From the tool's definition Tool name contains 'search' and description states 'Search for configuration items (CIs) in the CMDB' — a pure query/retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
Search for configuration items (CIs) in the CMDB. 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_cmdb_ci: 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_cmdb_ci 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_cmdb_ci 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_cmdb_ci. 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_cmdb_ci 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.
