1 | # WhatsApp Web MCP
2 |
3 | A powerful bridge between WhatsApp Web and AI models using the Model Context Protocol (MCP). This project enables AI models like Claude to interact with WhatsApp through a standardized interface, making it easy to automate and enhance WhatsApp interactions programmatically.
4 |
5 | ## Overview
6 |
7 | WhatsApp Web MCP provides a seamless integration between WhatsApp Web and AI models by:
8 | - Creating a standardized interface through the Model Context Protocol (MCP)
9 | - Offering MCP Server access to WhatsApp functionality
10 | - Providing flexible deployment options through SSE or Command modes
11 | - Supporting both direct WhatsApp client integration and API-based connectivity
12 |
13 | ## Disclaimer
14 |
15 | **IMPORTANT**: This tool is for testing purposes only and should not be used in production environments.
16 |
17 | Disclaimer from WhatsApp Web project:
18 |
19 | > This project is not affiliated, associated, authorized, endorsed by, or in any way officially connected with WhatsApp or any of its subsidiaries or its affiliates. The official WhatsApp website can be found at whatsapp.com. "WhatsApp" as well as related names, marks, emblems and images are registered trademarks of their respective owners. Also it is not guaranteed you will not be blocked by using this method. WhatsApp does not allow bots or unofficial clients on their platform, so this shouldn't be considered totally safe.
20 |
21 | ## Installation
22 |
23 | 1. Clone the repository:
24 | ```bash
25 | git clone https://github.com/pnizer/wweb-mcp.git
26 | cd wweb-mcp
27 | ```
28 |
29 | 2. Install globally or use with npx:
30 | ```bash
31 | # Install globally
32 | npm install -g .
33 |
34 | # Or use with npx directly
35 | npx .
36 | ```
37 |
38 | 3. Build with Docker:
39 | ```bash
40 | docker build . -t wweb-mcp:latest
41 | ```
42 |
43 | ## Configuration
44 |
45 | ### Command Line Options
46 |
47 | | Option | Alias | Description | Choices | Default |
48 | |--------|-------|-------------|---------|---------|
49 | | `--mode` | `-m` | Run mode | `mcp`, `whatsapp-api` | `mcp` |
50 | | `--mcp-mode` | `-c` | MCP connection mode | `standalone`, `api` | `standalone` |
51 | | `--transport` | `-t` | MCP transport mode | `sse`, `command` | `sse` |
52 | | `--sse-port` | `-p` | Port for SSE server | - | `3002` |
53 | | `--api-port` | - | Port for WhatsApp API server | - | `3001` |
54 | | `--auth-data-path` | `-a` | Path to store authentication data | - | `.wwebjs_auth` |
55 | | `--auth-strategy` | `-s` | Authentication strategy | `local`, `none` | `local` |
56 | | `--api-base-url` | `-b` | API base URL for MCP when using api mode | - | `http://localhost:3001/api` |
57 | | `--api-key` | `-k` | API key for WhatsApp Web REST API when using api mode | - | `''` |
58 |
59 | ### API Key Authentication
60 |
61 | When running in API mode, the WhatsApp API server requires authentication using an API key. The API key is automatically generated when you start the WhatsApp API server and is displayed in the logs:
62 |
63 | ```
64 | WhatsApp API key: 1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef
65 | ```
66 |
67 | To connect the MCP server to the WhatsApp API server, you need to provide this API key using the `--api-key` or `-k` option:
68 |
69 | ```bash
70 | npx wweb-mcp --mode mcp --mcp-mode api --api-base-url http://localhost:3001/api --api-key 1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef
71 | ```
72 |
73 | The API key is stored in the authentication data directory (specified by `--auth-data-path`) and persists between restarts of the WhatsApp API server.
74 |
75 | ### Authentication Methods
76 |
77 | #### Local Authentication (Recommended)
78 | - Scan QR code once
79 | - Credentials persist between sessions
80 | - More stable for long-term operation
81 |
82 | #### No Authentication
83 | - Default method
84 | - Requires QR code scan on each startup
85 | - Suitable for testing and development
86 |
87 | ## Usage

97 | #### MCP Server (Standalone)
98 | Run an MCP server that directly connects to WhatsApp Web:
99 | ```bash
100 | npx wweb-mcp --mode mcp --mcp-mode standalone --transport sse --sse-port 3002
101 | ```
102 |
103 | #### MCP Server (API Client)
104 | Run an MCP server that connects to the WhatsApp API server:

236 | ```
237 |
238 | 5. Restart Claude Desktop
239 | 6. The WhatsApp functionality will be available through Claude's interface
240 |
241 | ## Architecture
242 |
243 | The project is structured with a clean separation of concerns:
244 |
245 | ### Components
246 |
247 | 1. **WhatsAppService**: Core business logic for interacting with WhatsApp
248 | 2. **WhatsAppApiClient**: Client for connecting to the WhatsApp API
249 | 3. **API Router**: Express routes for the REST API
250 | 4. **MCP Server**: Model Context Protocol implementation
251 |
252 | ### Deployment Options
253 |
254 | 1. **WhatsApp API Server**: Standalone REST API server
255 | 2. **MCP Server (Standalone)**: Direct connection to WhatsApp Web
256 | 3. **MCP Server (API Client)**: Connection to WhatsApp API server
257 |
258 | This architecture allows for flexible deployment scenarios, including:
259 | - Running the API server and MCP server on different machines
260 | - Using the MCP server as a client to an existing API server
261 | - Running everything on a single machine for simplicity
262 |
263 | ## Development
264 |
265 | ### Project Structure
266 |
267 | ```
268 | src/
269 | ├── whatsapp-client.ts # WhatsApp Web client implementation
270 | ├── whatsapp-service.ts # Core business logic
271 | ├── whatsapp-api-client.ts # Client for the WhatsApp API
272 | ├── api.ts # REST API router
273 | ├── mcp-server.ts # MCP protocol implementation
274 | └── main.ts # Application entry point
275 | ```
276 |
277 | ### Building from Source
278 | ```bash
279 | npm run build
280 | ```
281 |
282 | ### Testing
283 |
284 | The project uses Jest for unit testing. To run the tests:
285 |
286 | ```bash
287 | # Run all tests
288 | npm test
289 |
290 | # Run tests in watch mode during development
291 | npm run test:watch
292 |
293 | # Generate test coverage report
294 | npm run test:coverage
295 | ```
296 |
297 | ### Linting and Formatting
298 |
299 | The project uses ESLint and Prettier for code quality and formatting:
300 |
301 | ```bash
302 | # Run linter
303 | npm run lint
304 |
305 | # Fix linting issues automatically
306 | npm run lint:fix
307 |
308 | # Format code with Prettier
309 | npm run format
310 |
311 | # Validate code (lint + test)
312 | npm run validate
313 | ```
314 |
315 | The linting configuration enforces TypeScript best practices and maintains consistent code style across the project.
316 |
317 | ## Troubleshooting
318 |
319 | ### Claude Desktop Integration Issues
320 | - It's not possible to start wweb-mcp in command standalone mode on Claude because Claude opens more than one process, multiple times, and each wweb-mcp needs to open a puppeteer session that cannot share the same WhatsApp authentication. Because of this limitation, we've split the app into MCP and API modes to allow for proper integration with Claude.
321 |
322 | ## Upcoming Features
323 |
324 | - Create webhooks for incoming messages and other WhatsApp events
325 | - Support for sending media files (images, audio, documents)
326 | - Group chat management features
327 | - Contact management (add/remove contacts)

347 | ### WhatsApp Web.js
348 |
349 | This project uses [whatsapp-web.js](https://github.com/pedroslopez/whatsapp-web.js), an unofficial JavaScript client library for WhatsApp Web that connects through the WhatsApp Web browser app. For more information, visit the [whatsapp-web.js GitHub repository](https://github.com/pedroslopez/whatsapp-web.js).

351 | ## License
352 |
353 | This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details.
354 |
355 | ## Logging
356 |
357 | WhatsApp Web MCP includes a robust logging system built with Winston. The logging system provides:
358 |
359 | - Multiple log levels (error, warn, info, http, debug)
360 | - Console output with colorized logs
361 | - HTTP request/response logging for API endpoints
362 | - Structured error handling
363 | - Environment-aware log levels (development vs. production)
364 | - All logs directed to stderr when running in MCP command mode
365 |
366 | ### Log Levels
367 |
368 | The application supports the following log levels, in order of verbosity:
369 |
370 | 1. **error** - Critical errors that prevent the application from functioning
371 | 2. **warn** - Warnings that don't stop the application but require attention
372 | 3. **info** - General information about application state and events
373 | 4. **http** - HTTP request/response logging
374 | 5. **debug** - Detailed debugging information
375 |
376 | ### Configuring Log Level
377 |
378 | You can configure the log level when starting the application using the `--log-level` or `-l` flag:
379 |
380 | ```bash
381 | npm start -- --log-level=debug
382 | ```
383 |
384 | Or when using the global installation:
385 |
386 | ```bash
387 | wweb-mcp --log-level=debug
388 | ```
389 |
390 | ### Command Mode Logging
391 |
392 | When running in MCP command mode (`--mode mcp --transport command`), all logs are directed to stderr. This is important for command-line tools where stdout might be used for data output while stderr is used for logging and diagnostics. This ensures that the MCP protocol communication over stdout is not interfered with by log messages.
393 |
394 | ### Test Environment
395 |
396 | In test environments (when `NODE_ENV=test` or when running with Jest), the logger automatically adjusts its behavior to be suitable for testing environments.
