transfer_account · CloudStack MCP Server MCP: Risk & Policy

WHAT IT DOES

What transfer_account does on CloudStack MCP Server

AI agents use transfer_account 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 transfer_account needs a policy

Transferring account ownership modifies the account's domain association, which is a reversible write operation (the account can be transferred back). However, it carries high severity because misuse by an AI agent could move accounts to unintended domains, potentially disrupting access control, permissions, and resource visibility across the CloudStack infrastructure.

Verdict

transfer_account Rate-limited

transfer_account 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.
