WHAT IT DOES

What disable_ha_for_zone does on CloudStack MCP Server

AI agents use disable_ha_for_zone 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 disable_ha_for_zone is rated Medium

Disabling HA for a zone is a reversible configuration change (it can be re-enabled), so it falls under Write rather than Destructive. However, the blast radius is high because it affects an entire zone's resilience, meaning all VMs in that zone lose automatic failover protection, which could cause widespread outages if VMs fail.

From the tool's definition 'Disable high availability for zone' — modifies the HA configuration for an entire zone
