import_vm · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What import_vm does on CloudStack MCP Server

AI agents use import_vm to create or update resources in CloudStack MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment.

WHY IT NEEDS A POLICY

Why import_vm needs a policy

Importing a VM creates a new virtual machine in the infrastructure, which is a reversible Write operation (the VM can be deleted). It is not Destructive because import does not delete or irreversibly overwrite data. It is not Execute because it doesn't run arbitrary code or trigger variable-outcome operations.

From the tool's definition Tool name 'import_vm' and description 'Import virtual machine' indicate creation or addition of a virtual machine resource to the CloudStack infrastructure.

Verdict

import_vm Rate-limited

import_vm stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What risk level is import_vm? +

import_vm is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit import_vm? +

Yes. Add a rate_limit block to the import_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 import_vm completely? +

Set action: deny in the PolicyLayer policy for import_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 import_vm? +

import_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.
