Arham Jewellers Server

MCP (Model Context Protocol) server for the Arham Jewellers customer AI assistant. Exposes tools for searching products, browsing categories, checking gold rates, tracking orders, placing orders, and getting store info.

Prerequisites

• Node.js 18+ (uses built-in fetch)
• A running Arham Jewellers backend API

Setup

# Install dependencies
npm install

# Configure environment
cp .env.example .env
# Edit .env with your API_BASE_URL

# Build
npm run build

Configuration

Create a .env file — only the API base URL is needed (token is passed per request):

API_BASE_URL=https://arham-jewellers-backend.onrender.com

Running

npm start

Get a Token

# Admin login (phone must include +91 prefix)
LOGIN_PHONE=+919879879870 LOGIN_PASSWORD=Admin@1234 npm run get-token

# User login
LOGIN_PHONE=+919879879870 LOGIN_PASSWORD=yourpass npm run get-token

Available Tools (11)

All tools require a token parameter (JWT) passed by the MCP client with each request.

Tool	Description
search_products	Search products by name, karat, or category
get_product_details	Get full details of a specific product
get_product_by_barcode	Find a product by barcode number
get_categories	Get the hierarchical category tree (Level 1=Karat, 2=Collection, 3=Style)
get_category_products	List products in a Level 3 category
get_current_gold_rate	Get today's gold rate per gram
get_gold_rate_history	Get historical gold rates
get_user_orders	Get order history
get_order_details	Get details of a specific order
place_order	Place an order (requires user confirmation)
get_store_info	Get store info (About, Contact, Terms, etc.)

Important Notes

• Category levels: Only Level 3 (Style) category IDs return products. Use get_categories(level=3) to find valid IDs.
• Order placement: place_order uses a two-step confirm flow — the AI must ask the user before setting confirm=true.
• Gold rate: The /api/v1/gold-rate/current endpoint may not be available on all backend versions.
