List all snapshots for a VM.
AI agents call list_vm_snapshots 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 queries and retrieves snapshot metadata for a virtual machine without modifying, creating, or destroying any data. It is a passive information-gathering operation consistent with the Read category. Low severity because snapshot listing poses minimal risk—it reveals only metadata about existing backups without exposing their content or enabling their modification/deletion.
From the tool's definition Tool name is 'list_vm_snapshots' and description states 'List all snapshots for a VM.' This is a retrieval operation with no modification or deletion capability. The server description explicitly confirms 'read-only interaction' and ability to 'view snapshots.
Attacks that exploit this kind of access
List all snapshots for a VM. 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 list_vm_snapshots: 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.
list_vm_snapshots 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 list_vm_snapshots 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 list_vm_snapshots. 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.
list_vm_snapshots is provided by the Proxmox MCP Server MCP server (teomarcdhio/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
