WHAT IT DOES

What add_guest_os_mapping does on CloudStack MCP Server

AI agents use add_guest_os_mapping 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 add_guest_os_mapping needs a policy

This tool creates or modifies a guest OS mapping, which is a configuration entity mapping guest operating systems to CloudStack hypervisor configurations. This is reversible (mappings can be updated or removed later) and has moderate blast radius if misconfigured—it could cause VMs launched with that mapping to fail or behave incorrectly, but does not directly delete data or execute arbitrary code.

From the tool's definition Tool name 'add_guest_os_mapping' indicates a creation/addition operation. The description 'Add guest OS mapping' confirms this creates a new guest OS mapping configuration in the CloudStack infrastructure.
