query_cluster_node_usage
AI agents call query_cluster_node_usage to retrieve information from OpenShift OVN-Kubernetes Benchmark MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and context suggest it retrieves cluster node usage metrics without modification. However, the empty description and potential for querying sensitive operational data in an OpenShift environment warrant medium severity due to information disclosure risk. Confidence is moderate because the actual scope and access controls are unknown.
From the tool's definition Tool name 'query_cluster_node_usage' indicates data retrieval (query pattern). Sibling tools on this server follow Read patterns (get_*, query_*). No description provided to confirm scope.
Attacks that exploit this kind of access
query_cluster_node_usage. It is categorised as a Read tool in the OpenShift OVN-Kubernetes Benchmark MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenShift OVN-Kubernetes Benchmark MCP Server MCP server in PolicyLayer and add a rule for query_cluster_node_usage: 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 OpenShift OVN-Kubernetes Benchmark MCP Server. Nothing to install.
query_cluster_node_usage 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 query_cluster_node_usage 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 query_cluster_node_usage. 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.
query_cluster_node_usage is provided by the OpenShift OVN-Kubernetes Benchmark MCP Server MCP server (liqcui/ovnk-benchmark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
query_cluster_node_usage is one line of OpenShift OVN-Kubernetes Benchmark 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.
