claude-whatsapp-mcp
WhatsApp MCP server for Claude Code. Read messages, send replies, search contacts — all from your terminal.
Built with whatsapp-web.js and the Model Context Protocol.
What it does
Give Claude Code direct access to your WhatsApp:
- Read chats — "check my unreads", "what did Ali say?"
- Send messages — "send John the proposal PDF"
- Search contacts — "find Sarah's number"
- Connection management — QR code auth, session persistence
Setup
1. Clone and install
git clone https://github.com/ferazfhansurie/claude-whatsapp-mcp.git
cd claude-whatsapp-mcp
npm install
2. Add to Claude Code
Add this to your Claude Code MCP settings (~/.claude.json or project .mcp.json):
{
"mcpServers": {
"whatsapp": {
"command": "node",
"args": ["/path/to/claude-whatsapp-mcp/src/index.js"]
}
}
}
3. Connect WhatsApp
In Claude Code, just say:
connect to whatsapp
Claude will initialize the server and show you a QR code. Scan it with your phone (WhatsApp > Settings > Linked Devices > Link a Device).
Your session persists in .wwebjs_auth/ — you only need to scan once.

How it works
The server runs whatsapp-web.js locally on your machine — the same tech as WhatsApp Web. Your messages stay on your device. Nothing is sent to any external server.
On first run, it generates a QR code for linking. After that, the session is cached and reconnects automatically.
