Why list_service_offerings needs a policy

This tool retrieves and queries available compute plans/service offerings from CloudStack. It performs a read-only operation that does not modify, execute, or delete any resources. The blast radius of misuse is minimal—an agent could only enumerate available service offerings, which is typically non-sensitive metadata. No credentials, financial transactions, or infrastructure changes occur.

From the tool's definition Tool name 'list_service_offerings' and description 'List service offerings (compute plans)' indicate data retrieval with no side effects.

POLICY

How to control list_service_offerings

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_service_offerings:

policy.json

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

list_service_offerings 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.
