## Why wavexis_webauthn_add_authenticator is rated High

This tool creates and registers a virtual WebAuthn authenticator in the browser environment. While it uses the word 'Add' (suggesting Write), it triggers an external browser operation that modifies the browser's authentication state and could be used to bypass or manipulate authentication flows. This makes it an Execute-level action, as it interacts with browser security mechanisms.

From the tool's own definition: "Add a virtual WebAuthn authenticator for testing"
