Quick Setup Guide

Step 1: Install Dependencies

First, make sure you have Python 3.11 or higher installed. Then:

Step 2: Set Up Environment Variables

Create a .env file in the project root:

Then edit .env and add your details:

Important Notes:

• AUTH_TOKEN: This is your secret token for authentication. Keep it safe!
• MY_NUMBER: Your WhatsApp number in format {country_code}{number} (e.g., 919876543210 for +91-9876543210)

Step 3: Run the Server

You'll see: 🚀 Starting MCP server on http://0.0.0.0:8086

Step 4: Make It Public (Required by Puch)

Since Puch needs to access your server over HTTPS, you need to expose your local server:

Option A: Using ngrok (Recommended)

1. Install ngrok: Download from https://ngrok.com/download
2. Get your authtoken:
   • Go to https://dashboard.ngrok.com/get-started/your-authtoken
   • Copy your authtoken
   • Run: ngrok config add-authtoken YOUR_AUTHTOKEN
3. Start the tunnel:
   ngrok http 8086

Option B: Deploy to Cloud

You can also deploy this to services like:

• Railway
• Render
• Heroku
• DigitalOcean App Platform

How to Connect with Puch AI

1. Open Puch AI in your browser
2. Start a new conversation
3. Use the connect command:
   /mcp connect https://your-domain.ngrok.app/mcp your_secret_token_here
