AI agents call k8s_node_list to retrieve information from Infra Ops without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about Kubernetes nodes without making any changes to the cluster. It is a read-only query operation that returns node status and resource metadata. The blast radius of misuse is minimal—an attacker could enumerate cluster infrastructure but cannot modify, execute, or delete resources.
From the tool's definition Tool name and description indicate listing/querying operation: 'List Kubernetes cluster nodes with their status and resource info'. No modifications, deletions, or execution of commands are performed.
Attacks that exploit this kind of access
List Kubernetes cluster nodes with their status and resource info. It is categorised as a Read tool in the Infra Ops MCP Server, which means it retrieves data without modifying state.
Register the Infra Ops MCP server in PolicyLayer and add a rule for k8s_node_list: 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 Infra Ops. Nothing to install.
k8s_node_list 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 k8s_node_list 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 k8s_node_list. 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.
k8s_node_list is provided by the Infra Ops MCP server (skyvanguard/infra-ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
