The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of JSON Web Token, so you can see the experience inside your AI.

It does not authenticate your account with JSON Web Token. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
