Query Kubernetes API server performance metrics including request rates,
AI agents call query_kube_api_metrics 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.
This tool retrieves performance metrics from the Kubernetes API server (request rates, etc.) without creating, modifying, deleting, or executing arbitrary operations. It is a read-only query operation.
From the tool's definition Tool name 'query_kube_api_metrics' and description 'Query Kubernetes API server performance metrics including request rates' indicate data retrieval operations with no modification or deletion of resources.
Attacks that exploit this kind of access
Query Kubernetes API server performance metrics including request rates,. 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_kube_api_metrics: 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_kube_api_metrics 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_kube_api_metrics 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_kube_api_metrics. 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_kube_api_metrics 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.
