🎯 Deal Radar MCP Server

Universal E-Commerce Price Drop, Deals & Multi-Store Radar for AI Agents
Powered by the Model Context Protocol (MCP)

Deal Radar MCP empowers AI assistants (Claude, Cursor, Antigravity, Gemini, Zed) to monitor e-commerce prices, uncover trending discounts, calculate real effective prices (including bank/coupon offers), track historical lows, and fire alerts when prices drop to your target.

Built with an extensible, plug-and-play adapter architecture, Deal Radar works out-of-the-box with Amazon, Flipkart, Croma, Myntra, Reliance Digital, Tata CLiQ, eBay, plus a universal Schema.org/OpenGraph fallback scraper that extracts product details and prices from virtually any online store.

🌟 Key Features

• 🔍 Multi-Store Price Comparison: Search Amazon, Flipkart, Croma, Myntra, Reliance Digital, and eBay in parallel to find the lowest price in seconds.

• 💳 Effective Price Intelligence: Calculates true out-of-pocket costs by factoring in instant bank discounts (HDFC, ICICI, Axis), coupon codes, and delivery charges.

• 📉 Persistent Watchlist & History: Automatically snapshots prices over time to pinpoint all-time lows and detect artificial markup before sales.

• 🔔 Autonomous Price Drop Alerts & Poller: Background cron engine periodically audits watchlist items and dispatches desktop notifications and MCP alerts.

• 🖥️ Interactive Web Dashboard: Beautiful local web UI (http://localhost:3333) for visual tracking, price comparisons, and one-click alert management.

• ⌨️ Command-Line Interface (CLI): Full-featured CLI tool (deal-radar search, deal-radar track, deal-radar alert, etc.).

• 🔌 Dynamic Store Adapters: Add any new store by dropping a JSON configuration in stores/ or dynamically registering via MCP.
