Getting Started with MCP Integration

Follow our comprehensive guide to connect the MCP server to Claude and start sending WhatsApp messages through your AI assistant. The MCP server provides a standardized interface that allows Claude to send WhatsApp messages through your optimatrix account in a simple and secure way.

⚠️
Note: Remote MCP connections are still early and may fail or require multiple attempts. If you experience issues, try restarting the application or disabling and re-enabling the optimatrix MCP server. Currently, the server provides the send_message tool for automated WhatsApp messaging.

Claude Desktop Setup

1. Open your Claude Desktop configuration file:

Open Claude Desktop Settings → Access Developer Settings → Edit Config to configure the Filesystem Server.
Alternatively, access directly:

# macOS
~/Library/Application Support/Claude/claude_desktop_config.json

# Windows
%APPDATA%\Claude\claude_desktop_config.json
2. Add the following configuration and restart:

Standard Configuration (https://app.optimatrix.ai):

{ "mcpServers": { "whatsapp-optimatrix": { "command": "npx", "args": [ "-y", "mcp-remote", "https://app.optimatrix.ai/mcp-server/sse", "--header", "x-api-key:your_api_key_here", "--header", "x-phone-id:your_phone_id_here" ] } } }
3. Replace placeholder values with actual credentials:
x-api-key
x-phone-id

Note: x-phone-id is only required when you have multiple phone numbers linked to your account. If you have only one, this header can be omitted.

4. Ready to Go!

After restarting Claude Desktop, you should see "whatsapp-optimatrix" in your MCP connections and can start sending messages.
