List backups for a VM or container
AI agents call pve_list_backups 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.
The tool retrieves and displays backup information without modifying, deleting, executing code, or affecting any system state. It is a straightforward read operation against backup metadata.
From the tool's definition Tool name is 'pve_list_backups' and description states it 'List backups for a VM or container' — this is a query/retrieval operation with no side effects.

Register the Proxmox MCP Server MCP server in PolicyLayer and add a rule for pve_list_backups: 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_backups 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_backups 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_backups. 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_backups 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.
