THE RISK

Low Risk

Why list_ssh_key_pairs needs a policy

This tool retrieves and lists existing SSH key pair metadata from CloudStack without creating, modifying, deleting, or executing anything. It has no side effects and falls squarely within the Read category. Low severity since SSH key pair listing does not directly expose private keys or enable unauthorized access on its own; it merely enumerates public key identifiers.

From the tool's definition Tool name 'list_ssh_key_pairs' with description 'List SSH key pairs' indicates a query/retrieval operation with no modification or execution capability.

POLICY

How to control list_ssh_key_pairs

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

policy.json

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

list_ssh_key_pairs 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 CloudStack MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
