Amazon Product, Price, and Stock Tracker MCP Server

An MCP server for the Mamba Labs Amazon Product, Price, and Stock Tracker actor on Apify. Read Amazon prices and stock by ASIN or URL and get change rows between runs.

What it does

Give ASINs or product URLs on 9 Amazon marketplaces. You get one flat row per product with the buy box price, list price, stock, seller, and rating, read for that marketplace's own delivery country, plus a free change row when a price moved or a product went out of or back into stock since the last run.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

{
  "mcpServers": {
    "mamba-amazon-product-price-stock-tracker": {
      "command": "npx",
      "args": [
        "-y",
        "@mambalabsdev/mcp-amazon-product-price-stock-tracker"
      ],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Restart the client. The track_amazon_products tool appears.

Prerequisites

Node.js 18 or newer.
An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.

Example prompts

"What is the current price and stock of these Amazon ASINs?"
"Check amazon.de for this product and tell me who sells it."
"Which of my tracked Amazon products changed price since the last run?"

Tool

track_amazon_products. One tool. Example arguments:

{
  "products": [
    "B00MNV8E0C"
  ],
  "marketplace": "amazon.com"
}

Inputs

Every buyer facing input of the actor. Omitted inputs take the actor's own defaults.

Input	Type	Required	Description
`products`	array	no	ASINs or Amazon product URLs, up to 1,000 per run. A URL uses the marketplace in the URL; a bare ASIN uses the Marketplace setting.
`marketplace`	string	no	The store a bare ASIN is read from.
`track_changes`	boolean	no	true (default) or false. With true, the actor keeps each product's last reading in a key value store in your account, and a later run writes a change row when the price moves or the product goes out of or back into stock.
`state_key`	string	no	Optional name for the set of last readings, when you keep several separate tracking lists. Letters, numbers, dots, dashes, underscores.
`previous_snapshot`	array	no	Optional. Rows from an earlier run of this actor, as a JSON list. When given, changes are computed against these rows, not the stored readings.
`max_charge_usd`	string	no	Optional. The run stops before a charge that would pass this amount. Summary rows are always returned.
`proxy_mode`	string	no	auto (default): amazon.com and amazon.ca are read through the Apify proxy pool with residential as the fallback; other marketplaces use residential addresses in that country, because Amazon prices for the delivery country. residential: every product uses residential addresses in its marketplace country and is billed as product-row-local.
