Query Open vSwitch (OVS) performance metrics including CPU usage, memory consumption,
AI agents call query_ovnk_ovs_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 monitoring data from OVS infrastructure. It is a read-only query operation that gathers metrics for analysis purposes. While the description appears truncated, the stated purpose is data collection for benchmarking and performance monitoring, which is characteristic of Read operations. No side effects, state changes, or irreversible actions are indicated.
From the tool's definition Tool name 'query_ovnk_ovs_metrics' and description indicate querying/retrieving 'Open vSwitch (OVS) performance metrics including CPU usage, memory consumption' with no mention of modification, execution, deletion, or financial operations.
Attacks that exploit this kind of access
Query Open vSwitch (OVS) performance metrics including CPU usage, memory consumption,. 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_ovnk_ovs_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_ovnk_ovs_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_ovnk_ovs_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_ovnk_ovs_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_ovnk_ovs_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.
