RISK

Why VPS_attachPublicKeyV1 is rated Medium

This tool modifies VPS instance configuration by attaching public keys, which is a reversible write operation. While it could enable unauthorized access if misused with wrong keys, the operation itself is not destructive (keys can be detached) and doesn't execute commands directly.

From the tool's definition Tool description states "Attach existing public keys from your account to a specified virtual machine." The verb "attach" and the action of enabling SSH key authentication represent modification of VPS configuration.
