WHAT IT DOES

What scale_system_vm does on CloudStack MCP Server

AI agents invoke scale_system_vm to trigger actions in CloudStack 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 scale_system_vm is rated High

Scaling a system VM is an execute operation that triggers infrastructure modifications whose outcomes depend on the scaling parameters provided. While it modifies resources (potentially Write-like), the scaling of system VMs—which are critical to CloudStack infrastructure—constitutes an active operational execution with blast radius impact on system availability and performance.

From the tool's definition Tool name 'scale_system_vm' with description 'Scale system VM resources' indicates modification of compute resources for system virtual machines.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs scale_system_vm safely

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

scale_system_vm Rate-limited

scale_system_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 CloudStack MCP Server, apply this rule, and every scale_system_vm call is checked against it from then on.

FAQ

Questions about scale_system_vm

What does the scale_system_vm tool do? +

Scale system VM resources. It is categorised as a Execute tool in the CloudStack 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 scale_system_vm? +

Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for scale_system_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 CloudStack MCP Server. Nothing to install.

What risk level is scale_system_vm? +

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

Can I rate-limit scale_system_vm? +

Yes. Add a rate_limit block to the scale_system_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 scale_system_vm completely? +

Set action: deny in the PolicyLayer policy for scale_system_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 scale_system_vm? +

scale_system_vm is provided by the CloudStack MCP Server MCP server (mozg31337/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
