WHAT IT DOES

What enable_ha_for_host does on CloudStack MCP Server

RISK

Why enable_ha_for_host is rated Medium

This tool modifies the High Availability configuration of a host in CloudStack infrastructure. While not destructive (the change is reversible via a disable operation), it is a Write operation that alters infrastructure state and could have significant blast radius if misconfigured by an AI agent—potentially affecting workload availability and failover behavior across virtual machines.

From the tool's definition Tool name 'enable_ha_for_host' indicates modification of host configuration. Description 'Enable HA for host' shows it modifies host settings (High Availability). This is a state-changing operation on infrastructure.
