WHAT IT DOES

What mold_stopVirtualMachine does on ABLESTACK MOLD MCP Server

AI agents invoke mold_stopVirtualMachine to trigger actions in ABLESTACK MOLD 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.

WHY IT NEEDS A POLICY

Why mold_stopVirtualMachine needs a policy

This is an Execute-category tool because it runs an operation that triggers external effects on cloud infrastructure (stopping a virtual machine). While not immediately destructive (the VM is not deleted, just stopped), it performs an irreversible state change to running infrastructure and could cause significant service disruption if misused by an AI agent (e.g., stopping production VMs).

From the tool's definition Tool name 'mold_stopVirtualMachine' and description indicate it stops virtual machines with a forced option, returning a jobid. This triggers an external operation (stopping a VM) whose effects depend on which VM is targeted.
