✨ Overview
Puch AI is an intelligent assistant capable of automating tasks and retrieving information. This MCP server extends its capabilities by providing a secure, authenticated API endpoint that Puch AI can call to execute specific "tools."
This server enables Puch AI to:
- 🌐 Fetch Web Content: Scrape and process information from any URL on the internet.
- 🛒 Search for Products: Perform real-time product searches using Google Shopping to provide users with up-to-date recommendations.
- 📱 Integrate with WhatsApp: The server is architected to be the backbone of a full-fledged WhatsApp integration.
🏗️ How It Works
The server provides a single, powerful API endpoint that accepts requests to run a specific tool with given arguments. The process flow is as follows:
- Puch AI receives a user prompt (e.g., "Find me a good laptop for under $1000").
- Puch AI determines a tool is needed (e.g.,
search_for_products). - Puch AI sends a POST request to this MCP server's
/mcp/ endpoint, specifying the tool_name and arguments. - The MCP Server authenticates the request using the Bearer Token.
- The server executes the requested tool (e.g., calls the SerpApi for product results).
- The server formats and returns the result to Puch AI in a structured JSON format.
- Puch AI uses this information to formulate a natural language response for the user.
🔧 Installation & Setup
Follow these steps to get the MCP server running on your local machine.
Prerequisites
- Python 3.11+
- pip (Python package installer)
- Git
Step-by-Step Guide
- Clone the Repository
Open your terminal and clone the repository to your local machine.
git clone https://github.com/alok-ahirrao/Puch-AI-WhatsApp-Integration-MCP-Server.git
cd Puch-AI-WhatsApp-Integration-MCP-Server
- Create a Virtual Environment (Recommended)
It's best practice to create a virtual environment to manage project dependencies.
# For macOS/Linux
python3 -m venv venv
source venv/bin/activate
# For Windows
python -m venv venv
.\venv\Scripts\activate
- Install Dependencies
Install all the required Python packages from the
requirements.txt file.pip install -r requirements.txt
- Create and Configure the
.env File
Create a file named .env in the root directory of the project. This file will store your secret keys and configuration variables. Copy the following and replace the placeholder values.# Get your API key from https://serpapi.com/
SERPAPI_API_KEY=YOUR_SERPAPI_API_KEY
# Your WhatsApp phone number (e.g., 919876543210)
MY_NUMBER=YOUR_PHONE_NUMBER
# A strong, secret token for authenticating API requests
TOKEN=YOUR_SECURE_BEARER_TOKEN
- Run the Server
Start the FastAPI server using Uvicorn.The server should now be running at
http://127.0.0.1:8085.
MCP Server Setup Instructions
Follow the instructions below to set up your MCP server and complete the application process.
- Obtain an application key:Use the provided starter code to spin up a local MCP server. After running
/apply <TWITTER/LINKEDIN REPLY URL>, you will get an application key. - Create an MCP server:Now you need to create an MCP server using the starter code given in this gist to submit your resume.
- Connect Puch to your MCP server:Use this command to connect Puch with your MCP server:
/mcp connect <SERVER URL (should be publicly accesible)>/mcp <AUTH TOKEN> - Validate the auth token and phone number:Puch will run a validation check against your Auth token (application key) and phone number. Validation requires both the key and your phone number, formatted as {country_code}{number} — without the + symbol. Example: 919876543210 for an Indian number.
- Create a resume tool:Feed your resume to Puch: Create a tool that sends your resume in a format fit for an LLM.
- Resume Tool Requirement: Your server must include a resume tool that:
- Accepts a local file (your resume).
- Converts it to markdown text
- Submits the data to the Puch AI MCP endpoint as a string.
- Set up an ngrok server:To make your local server publicly accessible, you can use ngrok. Run the following command:
ngrok http 8085
🔑 Authentication
All requests to the /mcp/ endpoint must be authenticated using a Bearer Token. Include the token in the Authorization header of your request.
Authorization: Bearer YOUR_SECURE_BEARER_TOKEN
Replace YOUR_SECURE_BEARER_TOKEN with the value you set for TOKEN in your .env file. A request with a missing or invalid token will result in a 401 Unauthorized error.
The server exposes its capabilities through a set of tools. You can invoke a tool by sending a POST request to the /mcp/ endpoint.
