WHAT IT DOES

What add_vpn_user does on CloudStack MCP Server

AI agents use add_vpn_user 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.

RISK

Why add_vpn_user is rated Medium

This tool creates a new VPN user for remote access, which is a Write operation (creates data/credentials). It is reversible (users can be deleted or disabled). The severity is medium because misuse could grant unauthorized remote access to infrastructure, but the operation is not inherently destructive and doesn't directly execute arbitrary code or move money.

From the tool's definition Tool name 'add_vpn_user' and description 'Add VPN user for Remote Access VPN' indicate creation of a new VPN user account, which is a reversible write operation.

RECOMMENDED RULE

The rule that runs add_vpn_user safely

add_vpn_user Rate-limited

add_vpn_user 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.
