WHAT IT DOES

What attach_iso does on CloudStack MCP Server

AI agents use attach_iso 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.

RISK

Why attach_iso is rated Medium

This tool modifies VM state by attaching an ISO image, which is a reversible write operation. It does not delete data (ruling out Destructive), execute arbitrary code on the target system (ruling out Execute as primary category), or move money (ruling out Financial).

From the tool's definition Tool name 'attach_iso' and description 'Attach ISO to a virtual machine' indicates a modification operation on VM configuration. ISO attachment is a state change that modifies the VM's attached media, though the operation is reversible (ISO can be detached).

RECOMMENDED RULE

The rule that runs attach_iso 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 attach_iso, this is the rule to start with:

attach_iso Rate-limited

attach_iso 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.
