AI agents call pve_get_cluster_status 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 a read-only query of cluster metadata. It has no side effects, does not execute operations, and does not modify infrastructure state. The information returned (cluster status) is informational only. Even if an AI agent misuses this tool by making unnecessary calls, it cannot cause harm to the Proxmox infrastructure.
From the tool's definition Tool name 'pve_get_cluster_status' and description 'Return Proxmox cluster status' indicate a query operation that retrieves cluster state information without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Return Proxmox cluster status. 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_get_cluster_status: 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_get_cluster_status 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_get_cluster_status 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_get_cluster_status. 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_get_cluster_status 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.
