This WhatsApp MCP server allows you to connect your personal WhatsApp account to AI agents like Anthropic Claude, enabling them to search messages, find contacts, list chats, retrieve message history, and send messages. It uses TypeScript and the Baileys library to interface with WhatsApp Web's multi-device API, keeping your data stored locally.
The fastest way to install for Claude Desktop:
npx -y @smithery/cli install @jlucaso1/whatsapp-mcp-ts --client claude
Clone the repository:
git clone <repository-url> whatsapp-mcp-ts
cd whatsapp-mcp-ts
Install dependencies:
npm install
Start the server for first-time setup:
node src/main.ts
During first-time setup:
auth_info/
directory./data/whatsapp.db
)Create a JSON configuration file with the following structure:
{
"mcpServers": {
"whatsapp": {
"command": "node",
"args": [
"/absolute/path/to/whatsapp-mcp-ts/src/main.ts"
],
"timeout": 15,
"disabled": false
}
}
}
Replace /absolute/path/to/whatsapp-mcp-ts
with the actual absolute path to your installation directory.
Claude Desktop:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
Cursor:
~/.cursor/mcp.json
After saving the configuration, restart your AI client so it can detect the WhatsApp MCP server.
Once connected, you can ask your AI assistant to:
The server exposes these capabilities to the AI:
./auth_info/
directory and restart the server./auth_info/
and ./data/
directories then restartwa-logs.txt
and mcp-logs.txt
for detailed error messages[email protected]
for users, [email protected]
for groups)wa-logs.txt
for specific errors from the Baileys libraryAll your WhatsApp data stays on your device:
./auth_info/
./data/whatsapp.db
(SQLite database)To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "whatsapp" '{"command":"node","args":["{{PATH_TO_REPO}}/src/main.ts"],"timeout":15,"disabled":false}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"whatsapp": {
"command": "node",
"args": [
"{{PATH_TO_REPO}}/src/main.ts"
],
"timeout": 15,
"disabled": false
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:

%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"whatsapp": {
"command": "node",
"args": [
"{{PATH_TO_REPO}}/src/main.ts"
],
"timeout": 15,
"disabled": false
}
}
}
3. Restart Claude Desktop for the changes to take effect
