Lists all cluster nodes with their status and resources
AI agents call k8s.get_nodes to retrieve information from K8s Mcp Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries node information from a Kubernetes cluster without creating, modifying, or deleting any resources. It has no side effects and fits the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch).' The low severity reflects that node information is non-sensitive cluster metadata with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_nodes' and description 'Lists all cluster nodes with their status and resources' indicate a retrieval operation with no modification capability. Server is explicitly described as 'read-only'.
Attacks that exploit this kind of access
Lists all cluster nodes with their status and resources. It is categorised as a Read tool in the K8s Mcp Assistant MCP Server, which means it retrieves data without modifying state.
Register the K8s Mcp Assistant MCP server in PolicyLayer and add a rule for 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 K8s Mcp Assistant. Nothing to install.
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 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 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.
k8s.get_nodes is provided by the K8s Mcp Assistant MCP server (nicolasmosquerar/k8s-mcp-assistant). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
