WHAT IT DOES

What get_cluster_resources does on Proxmox MCP Server

AI agents call get_cluster_resources to retrieve information from Proxmox MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_cluster_resources is rated Low

The tool performs a read-only operation that retrieves information about cluster resources (VMs, containers, storage, nodes) without creating, modifying, deleting, or executing any changes. It has no side effects and poses minimal risk if misused by an AI agent, as it only exposes existing infrastructure metadata.

From the tool's definition Tool name and description indicate it 'List[s] all resources across the cluster' with no modification, deletion, or execution capabilities. This is a query/retrieval operation.

RECOMMENDED RULE

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

get_cluster_resources Allowed

get_cluster_resources is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every get_cluster_resources call is checked against it from then on.
