Priceminder MCP Server

中文 | English

Priceminder — Real-time Shopee competitor price monitoring, powered by AI agents through the Model Context Protocol (MCP).

🌐 Sign up free: priceminder.online

Monitor competitor prices across Shopee Southeast Asia (SG, MY, TH, VN, ID, PH). Let your AI agent track, analyze, and alert on price movements — all through natural language.

📌 Important: Understand the Data Pipeline First

Priceminder's MCP service does not work standalone. It depends on competitor price data obtained through paid third-party API data services. Please understand this 3-layer pipeline before using:

Install Extension → Follow products you want to watch → Backend fetches data via paid APIs → AI Can Query

⚠️ Prerequisites

🔑 Where to get your MCP Key? The MCP Key is displayed in the browser extension settings page. No extension → No Key → No MCP service. The website registration (priceminder.online) is for account management and Pro upgrades — the MCP access credential lives inside the extension.

🤖 AI Capability Boundaries

Priceminder's MCP tools can only query products you've manually added to your monitoring list. It cannot arbitrarily search all of Shopee.

In short: You tell the system which competitors to watch, MCP lets AI analyze what's been collected.

For full capability details, see the MCP Tools Overview →

📊 Why Priceminder?

Real-time, not yesterday. Most price monitoring tools — including alternative MCP servers — return T-1 (yesterday's cached) data. Priceminder crawls prices 3 times daily, giving you near-real-time visibility.

In short: If you're using other tools, you're making decisions on yesterday's data. Priceminder tells you what's happening right now — and pushes alerts when competitors move.

🌟 Features — 8 MCP Tools

🚀 Quick Start

Install Extension → Add Products → Get MCP Key → Configure AI Client

For visual step-by-step guide with screenshots, see the official docs: Quick Start Guide →

Step 1: Install the Browser Extension

See Extension Installation Guide → for screenshots.

Step 2: Add Products to Monitor

Open any Shopee product page (supports SG/MY/TH/ID/TW/PH/VN). A "Monitor Now" button will appear at the top-right:

1. Click "Monitor Now" → product added to your monitor list
2. The system automatically starts collecting price data at your chosen interval
3. Configure crawl frequency and alert thresholds in the extension settings

💡 You need monitored products first. Without them, the AI will return empty results when queried. Start by adding at least 5–10 competitor products.

Step 3: Get Your MCP Key

Open the browser extension settings page. Your MCP Key is displayed in the "MCP Configuration" section.

⚠️ The MCP Key is only visible inside the extension settings. It is not available from the website login.

Step 4: Configure Your AI Client

Supported AI Clients (HTTP mode — recommended):

Add this URL (replace *** with your MCP Key):

{
  "mcpServers": {
    "sentinel": {
      "url": "https://priceminder.online/mcp_server?key=***"
    }
  }
}

Step 5: Verify the Connection

Test your setup by asking these questions:

✅ If the AI returns your monitoring data, setup is successful.

❌ If results are empty, make sure you've added products to monitor via the extension first.

💬 Prompt Scenarios

Here are 3 real-world scenarios you can run — each demonstrates a different use case:

1️⃣ Store-Level Price Watch

"Monitor all products from Shopee store 'ABC Official Store' on Shopee SG. If any product drops more than 5% in the last 24 hours, summarize the changes."

Your AI agent will:

1. Check your monitor list for this store's products
2. Compare latest crawl prices
3. Return products that dropped below the threshold

Best for: Brand competition — keep tabs on a specific competitor's entire catalog.

2️⃣ Flash Sale / Campaign Alert

"Check every 4 hours during the 7.7 sale — alert me if any of my tracked products have a price change of 3% or more. Show only the products that changed."

Your AI agent will:

1. Call get_price_summary to get current vs previous prices
2. Filter for products with ≥3% movement
3. Present a clean before/after comparison

Best for: Campaign periods — don't wake up to yesterday's data when competitors adjust prices hourly.

3️⃣ Price Drop Intelligence

"Show me all price drop alerts from the last 2 days. Which products dropped the most? Highlight any drops over 10%."

Your AI agent will:

1. Call get_alerts for recent notifications
2. Call get_price_history on the biggest movers for context
3. Rank by drop percentage and highlight critical moves

Best for: Buying decisions — spot the deepest discounts.
