Get detailed information about a specific node
AI agents call k8s_get_node to retrieve information from Kubernetes 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 node metadata and status from a Kubernetes cluster without making any changes. It is a query operation that has no side effects. Even though it relates to Kubernetes cluster infrastructure, the blast radius of misuse is limited to information disclosure about node configuration, capacity, and status—all typically non-sensitive operational metadata. This falls squarely into the Read category.
From the tool's definition Tool name and description indicate retrieval of information: 'Get detailed information about a specific node'. The verb 'Get' and the absence of any modification, execution, or deletion language clearly indicate a read-only operation.
Attacks that exploit this kind of access
Get detailed information about a specific node. It is categorised as a Read tool in the Kubernetes MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server MCP server in PolicyLayer and add a rule for k8s_get_node: 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. Nothing to install.
k8s_get_node 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_node 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_node. 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_node is provided by the Kubernetes MCP Server MCP server (mjrestivo16/mcp-kubernetes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
