count_cis
AI agents call count_cis to retrieve information from ServiceNow CMDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Counting CIs is a data retrieval operation with no modification, deletion, or execution side effects. It queries the CMDB to obtain a metric, consistent with the 'Read' category. The tool name and server context (CMDB querying focus) strongly suggest a non-destructive query operation. Low severity because miscounting CIs has minimal blast radius.
From the tool's definition Tool name 'count_cis' indicates a counting/enumeration operation on Configuration Items. The server description emphasizes 'querying' and 'dependency analysis' as primary capabilities.
Attacks that exploit this kind of access
count_cis. It is categorised as a Read tool in the ServiceNow CMDB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow CMDB MCP Server MCP server in PolicyLayer and add a rule for count_cis: 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 CMDB MCP Server. Nothing to install.
count_cis 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 count_cis 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 count_cis. 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.
count_cis is provided by the ServiceNow CMDB MCP Server MCP server (ketiil/mcp-cmdb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
count_cis is one line of ServiceNow CMDB MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
