register_iso · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What register_iso does on CloudStack MCP Server

AI agents use register_iso 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 register_iso needs a policy

Registering an ISO creates a new artifact in the CloudStack system. While this can be undone (unregister_iso would reverse it), it represents a write operation that modifies the infrastructure state.

From the tool's definition The tool 'register_iso' performs a registration operation that creates a new ISO resource in CloudStack infrastructure from an external URL. This is a reversible data modification operation (create/upload pattern).

register_iso Rate-limited

register_iso 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.
