List all VMs across the cluster or on a specific node
AI agents call pve_list_vms to retrieve information from Proxmox MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to enumerate virtual machines. Listing VMs has no side effects and cannot alter infrastructure state. While enumeration could inform reconnaissance in a multi-tenant or sensitive environment, the read-only nature and lack of capability to trigger actions places this in the Read category with low severity.
From the tool's definition Tool name 'pve_list_vms' and description 'List all VMs across the cluster or on a specific node' indicate a query operation that retrieves information without modifying or executing anything.
Attacks that exploit this kind of access
List all VMs across the cluster or on a specific node. It is categorised as a Read tool in the Proxmox MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Proxmox MCP Server MCP server in PolicyLayer and add a rule for pve_list_vms: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Proxmox MCP Server. Nothing to install.
pve_list_vms is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pve_list_vms rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for pve_list_vms. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
pve_list_vms is provided by the Proxmox MCP Server MCP server (mjrestivo16/mcp-proxmox). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
