Using pip

cd whatsapp-mcp
pip install -e .

Connect to Claude Desktop

1. Open config file:

   open ~/Library/Application\ Support/Claude/claude_desktop_config.json
   

   If it doesn't exist, create it.

2. Add the WhatsApp MCP server:

   {
     "mcpServers": {
       "whatsapp": {
         "command": "python3",
         "args": ["-m", "whatsapp_mcp"]
       }
     }
   }
   

3. Restart Claude Desktop (Cmd+Q, then reopen)

4. Look for the MCP tools icon (🔨) in the chat input — click it to verify "whatsapp" is listed

5. Start chatting:

   • "Show my recent WhatsApp chats"
   • "Search messages for dinner plans"

Connect to Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "whatsapp": {
      "command": "python3",
      "args": ["-m", "whatsapp_mcp"]
    }
  }
}

Restart Cursor and use WhatsApp tools in the AI chat.

Usage

Reading messages (works immediately)

Just ask Claude:

• "Show my recent WhatsApp chats"
• "Search for messages about dinner"
• "What did John say yesterday?"
• "Catch me up on unread messages"

Sending messages (requires bridge)

1. Start the WhatsApp bridge:

   cd bridge && npm install && npm start
   

2. Ask Claude to check connection:

   • "Check WhatsApp status"

3. If it shows a QR code, open the data URL in a browser and scan with your phone

4. Once connected, you can send:

   • "Send a message to Mom saying I'll be late"
   • "Reply to John with 'sounds good'"

How it works

Claude ──MCP──▶ WhatsApp MCP Server
                       │
                       ├──▶ Local SQLite DBs (read messages)
                       │    ~/Library/Group Containers/group.net.whatsapp.WhatsApp.shared/
                       │
                       └──▶ WhatsApp Bridge (:3010) ──▶ WhatsApp Web
                            (for sending)

Read operations query the local WhatsApp database directly — fast and works offline.

Send operations go through the bridge, which connects to WhatsApp Web using Baileys.
