WHAT IT DOES

What create_zfs_pool does on Proxmox MCP Server

AI agents use create_zfs_pool 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_zfs_pool is rated Medium

Creating a ZFS pool allocates and configures storage infrastructure but is not inherently destructive—pools can be removed later. However, this ranks as high severity due to the potential blast radius: misconfigured pools could impact system stability, cause data loss if improperly sized or placed, or consume significant resources.

From the tool's definition Tool name 'create_zfs_pool' combined with Proxmox VE infrastructure context indicates creation of persistent storage pool resources. This is a reversible modification operation (pools can be deleted), not irreversible destruction.

RECOMMENDED RULE

The rule that runs create_zfs_pool 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_zfs_pool, this is the rule to start with:

create_zfs_pool Rate-limited

create_zfs_pool 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.
