Get complete information about a specific configuration item
AI agents call get_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 ServiceNow's CMDB without creating, modifying, deleting, or executing any operations. It is a straightforward data query with no reversible or irreversible side effects. The blast radius of misuse is limited to information disclosure of existing configuration data.
From the tool's definition Tool name 'get_cmdb_ci' and description 'Get complete information about a specific configuration item' indicate data retrieval with no modification or side effects. CMDB (Configuration Management Database) queries are read-only operations.

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