Get Kubernetes cluster information including server version and endpoints
AI agents call k8s_get_cluster_info 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 cluster metadata (version, endpoints) without creating, modifying, or deleting resources. It is a read-only query operation with no side effects. The low severity reflects that cluster info is typically non-sensitive operational metadata, though in a security context it could inform reconnaissance. Confidence is high due to clear read-only semantics in both name and description.
From the tool's definition Tool name 'k8s_get_cluster_info' and description 'Get Kubernetes cluster information including server version and endpoints' indicate pure information retrieval with no state modification.
Attacks that exploit this kind of access
Get Kubernetes cluster information including server version and endpoints. 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_cluster_info: 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_cluster_info 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_cluster_info 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_cluster_info. 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_cluster_info 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.
