WHAT IT DOES

What create_directory_storage does on Proxmox MCP Server

AI agents use create_directory_storage to create or update resources in Proxmox MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Proxmox MCP Server environment.

RISK

Why create_directory_storage is rated Medium

This tool creates a new storage mount, which modifies the Proxmox infrastructure persistently. While the action is technically reversible (a storage mount can be unmounted and removed), it is a Write operation that establishes new storage bindings in the system. It is not Destructive because the storage itself is not deleted or permanently lost. It is not Financial or Execute.

From the tool's definition Tool name 'create_directory_storage' and description 'Create a directory-based storage mount from a device' indicate persistent creation of storage infrastructure resources.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_directory_storage safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Proxmox MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_directory_storage, this is the rule to start with:

create_directory_storage Rate-limited

create_directory_storage stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
