WHAT IT DOES

What create_storage does on Proxmox MCP Server

AI agents use create_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_storage is rated Medium

The tool creates (rather than deletes or modifies existing) storage resources in Proxmox infrastructure. This is reversible via deletion, placing it in Write category rather than Destructive. Severity is high because misconfigured storage allocation could consume quota, impact cluster resources, or disrupt service availability, though it lacks the irreversibility of Destructive actions or financial impact.

From the tool's definition Tool name 'create_storage' combined with server context (Proxmox VE infrastructure management) indicating creation of storage volumes/resources. Description is empty, limiting precision.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_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_storage, this is the rule to start with:

create_storage Rate-limited

create_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.
