Why get_k8s_resource_details needs a policy

This tool retrieves and returns information about Kubernetes resources (their manifests/configuration). It is a read-only operation with no side effects—it does not create, modify, delete, or execute any actions. The blast radius of misuse is low, as an agent could only gain visibility into existing cluster configurations, which aligns with the Read category for security catalogue tools.

From the tool's definition Tool name 'get_k8s_resource_details' and description 'Get the latest manifest of a Kubernetes resource' indicate a retrieval operation that queries and returns existing Kubernetes resource metadata/configuration without modification.

POLICY

How to control get_k8s_resource_details

PolicyLayer is an MCP gateway — it sits between your AI agents and RAD Security, and nothing reaches the server without passing your rules. This is the rule we recommend for get_k8s_resource_details:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_k8s_resource_details": {}
  }
}

get_k8s_resource_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register RAD Security — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
