Volt Cloud

Volt Cloud is a secure cloud connection to your WhatsApp account that powers Volt’s cloud-based features — starting with the MCP server, which lets AI assistants like Claude and ChatGPT read and send WhatsApp messages on your behalf.

How it works

Volt Cloud links your WhatsApp account the same way a second linked device does — by scanning a QR code. Once connected, Volt’s cloud infrastructure can serve requests from connected tools even when your computer is asleep or Volt isn’t running.

What it’s used for

Powering the MCP server, so AI clients can send messages, search contacts, and manage chats.
Delivering scheduled messages, so they still go out even when your computer is asleep or Volt isn’t running.
Future cloud-based features that don’t require your desktop app to be open.

Where to find it

Scheduled messages that need Volt Cloud to send prompt you to connect it right from the Send Later panel:

You’ll also find a red square in the bottom left of Volt when Volt Cloud is disconnected:

Privacy & data
