AI agents call pve_list_resources to retrieve information from Proxmox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only inspection of Proxmox cluster resources. The verb 'list' combined with optional filtering is a classic retrieval pattern with no side effects. It aligns with the server's stated capability for 'read-only cluster inspection.' No data is created, modified, deleted, or executed—only retrieved.
From the tool's definition Tool name 'pve_list_resources' and description 'List cluster resources, optionally filtered by type' indicate a query operation that retrieves information about cluster resources without modifying or executing operations.
Attacks that exploit this kind of access
List cluster resources, optionally filtered by type such as vm, storage, node. It is categorised as a Read tool in the Proxmox MCP Server, which means it retrieves data without modifying state.
Register the Proxmox MCP server in PolicyLayer and add a rule for pve_list_resources: 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. Nothing to install.
pve_list_resources 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_resources 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_resources. 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_resources is provided by the Proxmox MCP server (plgonzalezrx8/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
