WHAT IT DOES

What provision_vm_with_script does on Morpheus MCP Server

AI agents invoke provision_vm_with_script to trigger actions in Morpheus 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 provision_vm_with_script needs a policy

Provisioning a VM with a script combines resource creation with arbitrary code execution. The script component elevates this beyond a simple Write operation to Execute, as scripts can have wide-ranging effects on infrastructure. The blast radius is critical because misuse could spin up expensive cloud resources and execute malicious code in a multi-tenant environment.

From the tool's definition Tool name 'provision_vm_with_script' implies both provisioning a VM (Write/Execute) and executing a script during provisioning. The server description mentions 'provision resources' and 'execute workflows'.
