Why k8s_get_roles needs a policy

This tool retrieves and displays existing RBAC role configurations without altering them. It is a read-only operation that queries cluster state for informational purposes. While knowledge of roles could inform privilege escalation attempts, the tool itself performs no destructive, write, or execute operations. Classification as Read is appropriate.

From the tool's definition Tool name is 'k8s_get_roles' and description states 'List RBAC Roles with their permission rules.' The verb 'List' indicates data retrieval with no modifications or side effects.

How to control k8s_get_roles

PolicyLayer is an MCP gateway — it sits between your AI agents and Multi Cluster Kubernetes MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for k8s_get_roles:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "k8s_get_roles": {}
  }
}

k8s_get_roles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Multi Cluster Kubernetes MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
