reset_vm_password · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What reset_vm_password does on CloudStack MCP Server

AI agents use reset_vm_password 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 reset_vm_password needs a policy

Resetting a VM password modifies authentication credentials for the virtual machine. This is reversible (a new password can be set again) so it falls under Write rather than Destructive. However, it carries high severity because an AI agent misusing this tool could lock out legitimate users or facilitate unauthorized access to VMs by changing credentials to unknown values.

From the tool's definition 'Reset virtual machine password' — resets the password on a VM, which is a credential modification operation

reset_vm_password Rate-limited

reset_vm_password 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.
