WHAT IT DOES

What list_isos does on CloudStack MCP Server

AI agents call list_isos to retrieve information from CloudStack MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_isos is rated Low

This tool retrieves and lists ISO images available in the CloudStack infrastructure. It performs a read-only query operation that does not modify, delete, or execute any operations on the infrastructure. The verb 'list' combined with the passive nature of querying available resources confirms this is a Read category tool with low severity and blast radius.

From the tool's definition Tool name 'list_isos' and description 'List ISOs available in CloudStack' indicate a query/retrieval operation with no side effects.

list_isos Allowed

list_isos is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
