WHAT IT DOES

What suspend_vm does on Proxmox MCP Server

AI agents invoke suspend_vm to trigger actions in Proxmox MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why suspend_vm is rated High

Suspending a VM pauses or hibernates its execution, which is an operational state change that affects running workloads. This is an Execute action as it triggers an external operation (changing VM state) whose effects depend on arguments.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs suspend_vm safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Proxmox MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For suspend_vm, this is the rule to start with:

suspend_vm Rate-limited

suspend_vm stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every suspend_vm call is checked against it from then on.

FAQ

Questions about suspend_vm

What does the suspend_vm tool do? +

Suspend a VM (pause execution or hibernate to disk). It is categorised as a Execute tool in the Proxmox MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on suspend_vm? +

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

What risk level is suspend_vm? +

suspend_vm is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit suspend_vm? +

Yes. Add a rate_limit block to the suspend_vm 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.

How do I block suspend_vm completely? +

Set action: deny in the PolicyLayer policy for suspend_vm. 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.

What MCP server provides suspend_vm? +

suspend_vm is provided by the Proxmox MCP Server MCP server (gethosthewalrus/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
