WhatsApp MCP Server

A Model Context Protocol (MCP) server for WhatsApp integration. Send messages, search conversations, and access your WhatsApp history through Claude and other LLMs.

Overview

This MCP server provides 7 tools to interact with your WhatsApp account via the whatsmeow library:

• list_chats - List conversations with filtering, sorting, and pagination
• list_messages - Retrieve message history with date range filtering and context
• search_messages - Full-text search across all messages using SQLite FTS5 with context
• send_message - Send text and media messages with fuzzy name matching and reply/threading
• download_media - Download media files from conversations to local storage
• get_connection_status - Check WhatsApp connection status and database statistics
• catch_up - Intelligent activity summary showing recent chats, questions, and media

All messages and chats are persisted to a local SQLite database with full-text search capabilities, enabling rich queries and analysis of your WhatsApp history.

Prerequisites

• Docker

Installation & Setup

# Pull the image
docker pull ghcr.io/eddmann/whatsapp-mcp:latest

First Run - WhatsApp Pairing

# Create directory for persistent storage
mkdir -p whatsapp-store

# Run the container (QR code will be displayed)
docker run -it --rm \
  -v "$(pwd)/whatsapp-store:/app/store" \
  ghcr.io/eddmann/whatsapp-mcp:latest

On first run, a QR code will be displayed in the terminal:

1. Open WhatsApp on your phone
2. Go to Settings → Linked Devices → Link a Device
3. Scan the QR code displayed in your terminal
4. Wait for history sync to complete (check logs for "history sync persisted messages count=...")

Authentication & Data Storage

• Session Storage: WhatsApp session data is saved to store/whatsapp.db and persists across restarts
• Message Database: All messages and chats are stored in store/messages.db with FTS5 full-text search
• Media Downloads: Downloaded media files are organized in store/<chatJID>/ directories
• No Re-Authentication: After initial pairing, the server automatically reconnects using stored credentials

Important: Mount a volume to /app/store to persist session data and messages across container restarts.

Sending Messages

"Send a message to John saying I'll be there in 10 minutes"
"Send a photo from ~/Desktop/photo.jpg to Bob"
"Send this audio recording to the Project Team group"
"Reply to that message from Sarah saying 'Sounds good!'"

Recipient Formats (with fuzzy name matching):

• Contact/group names: "John", "Bob", "Project Team" (searches your chat history)
