AI agents call list_kubernetes_types to retrieve information from Linode 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 and lists available Kubernetes types from the Linode infrastructure—a pure information lookup with no side effects, resource creation, modification, or deletion. It is a read operation with minimal blast radius if misused by an AI agent, as it only exposes informational data about available options.
From the tool's definition Tool name 'list_kubernetes_types' and description 'List all available Kubernetes types' indicates a read-only query operation that retrieves information about available Kubernetes cluster types without modifying any resources.
Documented attack patterns abuse exactly the kind of access list_kubernetes_types gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_kubernetes_types:
{
"version": "1",
"default": "deny",
"tools": {
"list_kubernetes_types": {}
}
}list_kubernetes_types is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all available Kubernetes types. It is categorised as a Read tool in the Linode MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for list_kubernetes_types: 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 Linode MCP Server. Nothing to install.
list_kubernetes_types 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 list_kubernetes_types 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 list_kubernetes_types. 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.
list_kubernetes_types is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Linode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
