Puch AI MCP Starter

MCP Starter for Puch AI

This is a starter template for creating your own Model Context Protocol (MCP) server that works with Puch AI. It comes with ready-to-use tools for job searching and image processing.

What is MCP?

MCP (Model Context Protocol) allows AI assistants like Puch to connect to external tools and data sources safely. Think of it like giving your AI extra superpowers without compromising security.

What's Included in This Starter?

🎯 Job Finder Tool

• Analyze job descriptions - Paste any job description and get smart insights
• Fetch job postings from URLs - Give a job posting link and get the full details
• Search for jobs - Use natural language to find relevant job opportunities

🖼️ Image Processing Tool

• Convert images to black & white - Upload any image and get a monochrome version

🔐 Built-in Authentication

• Bearer token authentication (required by Puch AI)
• Validation tool that returns your phone number

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
