List cluster nodes with roles and DPDK/SR-IOV relevant details.
AI agents call tool_k8s_get_nodes to retrieve information from Kubernetes MCP Server – 5G Core Edition without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries Kubernetes cluster node information and their metadata (roles, DPDK/SR-IOV details). It performs no writes, deletes, executions, or financial operations. Misuse by an AI agent would only expose cluster topology information, which is informational and has minimal blast radius in a properly secured cluster. This is a standard read operation typical of cluster inspection tooling.
From the tool's definition Tool name 'k8s_get_nodes' and description 'List cluster nodes' indicate a read-only operation that retrieves cluster state without modification.
Attacks that exploit this kind of access
List cluster nodes with roles and DPDK/SR-IOV relevant details. It is categorised as a Read tool in the Kubernetes MCP Server – 5G Core Edition MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server – 5G Core Edition MCP server in PolicyLayer and add a rule for tool_k8s_get_nodes: 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 Kubernetes MCP Server – 5G Core Edition. Nothing to install.
tool_k8s_get_nodes 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 tool_k8s_get_nodes 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 tool_k8s_get_nodes. 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.
tool_k8s_get_nodes is provided by the Kubernetes MCP Server – 5G Core Edition MCP server (sanzco/mcp5g). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
