Step-by-Step Installation & Setup Guide
Prerequisites
- Go
- Python 3.6+
- Anthropic Claude Desktop app (or Cursor)
- UV (Python package manager), install with
curl -LsSf https://astral.sh/uv/install.sh | sh - FFmpeg (optional) - Only needed for audio messages.
Steps
-
Clone the Repository
git clone https://github.com/lharries/whatsapp-mcp.git cd whatsapp-mcp -
Run the WhatsApp Bridge
Navigate to the whatsapp-bridge directory and run the Go application:
cd whatsapp-bridge go run main.goThe first time you run it, you will be prompted to scan a QR code. Scan the QR code with your WhatsApp mobile app to authenticate.
-
Connect to the MCP Server
Copy the below JSON with the appropriate {{PATH}} values:
{ "mcpServers": { "whatsapp": { "command": "{{PATH_TO_UV}}", "args": [ "--directory", "{{PATH_TO_SRC}}/whatsapp-mcp/whatsapp-mcp-server", "run", "main.py" ] } } }For Claude, save this as
claude_desktop_config.jsonin your Claude Desktop configuration directory at:~/Library/Application Support/Claude/claude_desktop_config.jsonFor Cursor, save this as
mcp.jsonin your Cursor configuration directory at:~/.cursor/mcp.json -
Restart Claude Desktop / Cursor
Open Claude Desktop and you should now see WhatsApp as an available integration. Or restart Cursor.
Windows Compatibility
If you're running this project on Windows, be aware that go-sqlite3 requires CGO to be enabled in order to compile and work properly. By default, CGO is disabled on Windows, so you need to explicitly enable it and have a C compiler installed.
Steps to get it working:
-
Install a C compiler
We recommend using MSYS2 to install a C compiler for Windows. After installing MSYS2, make sure to add the
ucrt64\binfolder to yourPATH. -
Enable CGO and run the app
cd whatsapp-bridge go env -w CGO_ENABLED=1 go run main.goWithout this setup, you'll likely run into errors like:
Binary was compiled with 'CGO_ENABLED=0', go-sqlite3 requires cgo to work.
REAL Code Examples from the Repository
Example 1: Running the WhatsApp Bridge
# Navigate to the whatsapp-bridge directory
$ cd whatsapp-mcp/whatsapp-bridge
# Run the Go application
$ go run main.go
# Scan the QR code with your WhatsApp mobile app to authenticate
This command starts the WhatsApp bridge, which connects to the WhatsApp web API and handles authentication. The QR code displayed in the terminal needs to be scanned with your WhatsApp mobile app to complete the setup.
Example 2: Configuring Claude Desktop
{
"mcpServers": {
"whatsapp": {
"command": "/usr/local/bin/uv",
"args": [
"--directory",
"/path/to/whatsapp-mcp/whatsapp-mcp-server",
"run",
"main.py"
]
}
}
}
This JSON configuration file tells Claude Desktop how to connect to the WhatsApp MCP server. Replace {{PATH_TO_UV}} and {{PATH_TO_SRC}} with the actual paths on your system.
Example 3: Restarting Claude Desktop
# Restart Claude Desktop
$ killall claude-desktop && claude-desktop
This command restarts the Claude Desktop application, ensuring that the new WhatsApp integration is loaded.
