WHAT IT DOES

What setup_dev_environment does on Virtualbox MCP Server

AI agents invoke setup_dev_environment to trigger actions in Virtualbox 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 setup_dev_environment needs a policy

This tool executes installation commands inside a VM to set up software runtimes and dependencies. It triggers external operations (package installation, configuration changes) within the VM environment. Misuse could install malicious software, backdoors, or unwanted runtimes. It spans Write and Execute categories, but since it runs commands/scripts inside a VM, Execute is most appropriate.
