Why list_object_storage_quotas needs a policy

This tool retrieves and displays quota information for Object Storage resources. It performs a read-only operation that queries existing data without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an attacker could only learn quota limits, which is informational data with no direct impact on infrastructure or data integrity.

From the tool's definition Tool name 'list_object_storage_quotas' and description 'List Object Storage quotas' indicate a query/retrieval operation with no side effects.

POLICY

How to control list_object_storage_quotas

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_object_storage_quotas:

policy.json

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

list_object_storage_quotas 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 Linode 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.
