get_vm_metrics
AI agents call get_vm_metrics 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 VM performance metrics with no side effects. It fits the read-only pattern established by the server's design and comparable tools. No data modification, execution, or destructive capability is indicated. Low severity due to read-only nature and limited blast radius if misused by an agent.
From the tool's definition Tool name 'get_vm_metrics' combined with server description stating 'read-only interaction' and 'monitor status and performance metrics'. Sibling tools (get_cluster_status, get_vm_info, get_vm_status, list_vms) are all Read operations.
Attacks that exploit this kind of access
get_vm_metrics. 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 get_vm_metrics: 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.
get_vm_metrics 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 get_vm_metrics 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 get_vm_metrics. 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.
get_vm_metrics 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.
