## Support for `ARM` & `AMD` Architecture along with `MCP` Support

Download:

- [Release](https://github.com/aldinokemal/go-whatsapp-web-multidevice/releases/latest)
- [Docker Hub](https://hub.docker.com/r/aldinokemal2104/go-whatsapp-web-multidevice/tags)
- [GitHub Container Registry](https://github.com/aldinokemal/go-whatsapp-web-multidevice/pkgs/container/go-whatsapp-web-multidevice)

## Support n8n package (n8n.io)

- [n8n package](https://www.npmjs.com/package/@aldinokemal2104/n8n-nodes-gowa)
- Go to Settings -> Community Nodes -> Input `@aldinokemal2104/n8n-nodes-gowa` -> Install

## Breaking Changes

- `v6`
  - For REST mode, you need to run ` rest` instead of ``
    - for example: `./whatsapp rest` instead of ~~./whatsapp~~
  - For MCP mode, you need to run ` mcp`
    - for example: `./whatsapp mcp`
- `v7`
  - Starting version 7.x we are using goreleaser to build the binary, so you can download the binary
      from [release](https://github.com/aldinokemal/go-whatsapp-web-multidevice/releases/latest)

## Feature

- Send WhatsApp message via http API, [docs/openapi.yml](./docs/openapi.yaml) for more details
- **MCP (Model Context Protocol) Server Support** - Integrate with AI agents and tools using standardized protocol
- Mention someone
  - `@phoneNumber`
  - example: `Hello @628974812XXXX, @628974812XXXX`
- Post Whatsapp Status
- Compress image before send
- Compress video before send
- Change OS name become your app (it's the device name when connect via mobile)
  - `--os=Chrome` or `--os=MyApplication`
- Basic Auth (able to add multi credentials)
  - `--basic-auth=kemal:secret,toni:password,userName:secretPassword`, or you can simplify
  - `-b=kemal:secret,toni:password,userName:secretPassword`
- Subpath deployment support
  - `--base-path="/gowa"` (allows deployment under a specific path like `/gowa/sub/path`)
- Customizable port and debug mode
  - `--port 8000`
  - `--debug true`
- Auto reply message
  - `--autoreply="Don't reply this message"`
- Auto mark read incoming messages
  - `--auto-mark-read=true` (automatically marks incoming messages as read)
- Webhook for received message
  - `--webhook="http://yourwebhook.site/handler"`, or you can simplify
  - `-w="http://yourwebhook.site/handler"`
  - for more detail, see [Webhook Payload Documentation](./docs/webhook-payload.md)
- Webhook Secret
  Our webhook will be sent to you with an HMAC header and a sha256 default key `secret`.

  You may modify this by using the option below:
  - `--webhook-secret="secret"`
- **Webhook Payload Documentation**
  For detailed webhook payload schemas, security implementation, and integration examples,
  see [Webhook Payload Documentation](./docs/webhook-payload.md)

## Configuration

You can configure the application using either command-line flags (shown above) or environment variables. Configuration
can be set in three ways (in order of priority):

1. Command-line flags (highest priority)
2. Environment variables
3. `.env` file (lowest priority)

### Environment Variables

You can configure the application using environment variables. Configuration can be set in three ways (in order of
priority):

1. Command-line flags (highest priority)
2. Environment variables
3. `.env` file (lowest priority)

To use environment variables:

1. Copy `.env.example` to `.env` in your project root (`cp src/.env.example src/.env`)
2. Modify the values in `.env` according to your needs
3. Or set the same variables as system environment variables

### MCP Server (Model Context Protocol)

This application can also run as an MCP server, allowing AI agents and tools to interact with WhatsApp through a
standardized protocol.

1. Clone this repo `git clone https://github.com/aldinokemal/go-whatsapp-web-multidevice`
2. Open the folder that was cloned via cmd/terminal.
3. run `cd src`
4. run `go run . mcp` or build the binary and run `./whatsapp mcp`
5. The MCP server will start on `http://localhost:8080` by default

#### MCP Server Options

- `--host localhost` - Set the host for MCP server (default: localhost)
- `--port 8080` - Set the port for MCP server (default: 8080)

#### Available MCP Tools

- `whatsapp_send_text` - Send text messages
- `whatsapp_send_contact` - Send contact cards

```json
{
  "mcpServers": {
    "whatsapp": {
      "url": "http://localhost:8080/sse"
    }
  }
}
