A Model Context Protocol (MCP) server for [WSAPI](https://wsapi.chat) - the WhatsApp API Gateway. Enables LLMs to send messages, manage contacts and groups, handle communities and newsletters, post status updates, and more through WhatsApp.

For comprehensive documentation, see the [WSAPI MCP Server guide](https://docs.wsapi.chat/integrations/mcp-server).

> **Note**: This project is not affiliated with, associated with, or endorsed by WhatsApp or Meta.

## Installation

### Prerequisites
- Node.js >= 20.19.0
- WSAPI account with API credentials ([wsapi.chat](https://wsapi.chat))

### Claude Desktop

Add to your Claude Desktop configuration:

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "wsapi": {
      "command": "npx",
      "args": ["@wsapichat/mcp-server"],
      "env": {
        "WSAPI_API_KEY": "your_api_key_here",
        "WSAPI_INSTANCE_ID": "your_instance_id_here",
        "WSAPI_ENABLED_CATEGORIES": "messaging,contacts"
      }
    }
  }
}
```

### Claude Code

```bash
claude mcp add wsapi -- npx @wsapichat/mcp-server \
  --env WSAPI_API_KEY=your_api_key_here \
  --env WSAPI_INSTANCE_ID=your_instance_id_here \
  --env WSAPI_ENABLED_CATEGORIES=messaging,contacts
```

## Tool Filtering

The server exposes 80+ tools across 12 categories. To reduce context window usage, you can filter which tools are loaded using environment variables.

### By category

Load only messaging and contact tools:

```
WSAPI_ENABLED_CATEGORIES=messaging,contacts
```

Available categories: `messaging`, `contacts`, `groups`, `chats`, `session`, `users`, `communities`, `newsletters`, `status`, `calls`, `media`

### By individual tool

Load only specific tools:

```
WSAPI_ENABLED_TOOLS=whatsapp_send_text,whatsapp_send_image,whatsapp_get_contacts
```

### Combined

Use categories as a base set and add individual tools from other categories:

```
WSAPI_ENABLED_CATEGORIES=messaging
WSAPI_ENABLED_TOOLS=whatsapp_get_contacts,whatsapp_get_chats
```

If neither variable is set, all tools are loaded.
