Volt MCP: Run WhatsApp From Claude and ChatGPT

Releases

Volt now speaks MCP

WhatsApp lives in its own app, separate from wherever you actually get work done. Volt's new MCP server closes that gap. Connect it once, and Claude, ChatGPT, or any Model Context Protocol client can read your chats, send messages, manage contacts, and organize conversations, all without you touching your phone.

The server lives at mcp.voltchat.com/mcp and it's live today.

Get started in 30 seconds

For Claude, setup is a one-click connector: add Volt, sign in with your phone number, approve access. No config file, no API key.

Developer tools that don't support hosted OAuth connectors yet can still connect with a Volt API key. For Claude Code, that's one command:

claude mcp add --transport http volt https://mcp.voltchat.com/mcp --header "Authorization: Bearer YOUR_VOLT_API_KEY"

Claude Desktop, Cursor, Windsurf, Gemini CLI, and Zed all have setup configs too. Full instructions are in the setup guide.

What your AI assistant can actually do

Volt MCP ships with 18 tools, grouped into three areas:

  • Read and resolve: search contacts, list chats, read messages, browse chat lists
  • Send and organize: send messages, schedule messages, send broadcasts, add contacts, mark chats read or archived, add/remove chats from lists
  • Groups: create groups, add or remove participants, promote or demote admins

A couple of details worth knowing. get-chat-messages includes Volt's audio transcriptions, so your assistant can read voice notes, not just text. And send-broadcast is built for 4 or more recipients, delivering messages on a paced background schedule rather than all at once.

Beyond the tools, the server also exposes a whatsapp://status resource for checking connection state, plus a guided send-whatsapp prompt that walks through pre-flight checks before a message goes out.

What people are actually using it for

The point isn't the tool list, it's what you can ask for in plain language. A few real examples:

  • "Summarize my unread WhatsApp chats from today. Group them into urgent, needs a reply, and informational."
  • "Read my latest conversation with Maya, draft a concise reply that answers her questions, and ask me before sending it."
  • "Schedule a follow-up to Sam for next Monday at 9 AM asking whether they reviewed the proposal."
  • "Prepare a broadcast for the contacts in my Customers list announcing Friday's maintenance window. Keep it short and ask me to approve it before sending."
  • "Add every chat related to the Riverside project to my Riverside list."

More prompts and routines are in the use cases guide.

Where it connects

Volt MCP works with:

  • Claude, via one-click connector
  • ChatGPT, via custom connector
  • Claude Code, as a terminal and IDE agent
  • Codex, OpenAI's coding agent in ChatGPT
  • Cursor and other API-key clients

Privacy

MCP stores message content encrypted at rest. Disconnect the session, and the stored data is deleted with it.
