MCP 服务器

amazon-in-mcp

MCP server for amazon.in — cheapest in-stock, best-value picks, and price history links.

README

<h1 align="center">amazon-in-mcp</h1>

An <a href="https://modelcontextprotocol.io">MCP</a> server that lets your LLM shop on Amazon.in. Cheapest in-stock listing. Best-value pick. Price history. No paid APIs.

What it does

Three tools your LLM can call against amazon.in:

Tool	What it returns
`search_amazon_in(query, max_results=5)`	Ranked listings + two convenience picks: cheapest in stock and best value (rating × log10(reviews) / √price)
`get_product(asin_or_url)`	Full product detail — price, MRP, discount, rating, reviews, stock, bullets, brand, seller, delivery
`price_history_link(asin_or_url)`	A Keepa.com chart URL for the amazon.in domain. No network call.

No API keys. No accounts. Runs locally over stdio. Direct HTML scraping with rotating user agents and retry on bot-check pages.

Quick start

1. Install (Claude Code):

git clone https://github.com/justadityaraj/amazon-in-mcp.git
cd amazon-in-mcp && npm install && npm run build
claude mcp add amazon-in -- node "$PWD/dist/index.js"

2. Restart your MCP client (Claude Code, Cursor, Claude Desktop, etc.)

3. Ask:

"Find me a good 1TB external SSD on amazon.in under ₹10,000. Best value pick."

Your LLM will call search_amazon_in, rank by value, and hand back a real product with current price and a Keepa link for price history.

What it looks like

A real call to search_amazon_in("wireless mouse", max_results=3) returns:

{
  "query": "wireless mouse",
  "total_results": 3,
  "results": [
    {
      "asin": "B0CQRNWJM2",
      "title": "ZEBRONICS Blanc Slim Wireless Mouse...",
      "url": "https://www.amazon.in/dp/B0CQRNWJM2?tag=artech-21",
      "price_inr": 423,
      "mrp_inr": 799,
      "rating": 4.0,
      "review_count": 7801,
      "in_stock": true,
      "delivery": "FREE delivery Tomorrow",
      "price_history_url": "https://keepa.com/#!product/12-B0CQRNWJM2"
    }
  ],
  "cheapest_in_stock": { "asin": "...", "price_inr": 199, "...": "..." },
  "best_value":        { "asin": "...", "rating": 4.3, "...": "..." }
}

get_product adds bullets[], brand, seller, discount_percent, availability.

Configure your MCP client

<details> <summary>Claude Code</summary>

claude mcp add amazon-in -- node /absolute/path/to/amazon-in-mcp/dist/index.js

</details>

<details> <summary>Claude Desktop</summary>

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "amazon-in": {
      "command": "node",
      "args": ["/absolute/path/to/amazon-in-mcp/dist/index.js"]
    }
  }
}

</details>

<details> <summary>Cursor / Windsurf / others</summary>

Same JSON config as Claude Desktop. Drop it into the client's MCP settings file. </details>

Image search

The server intentionally doesn't accept image input — keeps it provider-agnostic. Instead, paste the image into your LLM client, ask it to describe the product, and it'll call search_amazon_in with the right keywords automatically. Works the same in every MCP-capable client.

How "best value" is scored

Among in-stock listings with at least 10 reviews:

$$ \text{score} = \frac{\text{rating} \times \log_{10}(\text{reviews} + 10)}{\sqrt{\text{price}}} $$

The highest score wins. cheapest_in_stock is just the lowest price_inr among in-stock items — useful when you want raw cheapness instead of balance.

Robustness


UA rotation	5 modern desktop UAs (Chrome / Safari / Firefox on Mac / Win / Linux)
Retries	3 attempts, exponential backoff on 5xx, 429, and bot-check pages
Bot detection	Scans first 8 KB for known CAPTCHA / robot markers
Timeout	20 s per request
State	None. Stdio, no cookies, no session

Expect ~1–5% of requests to fail with a bot-check during heavy use. Wait 30–60 seconds and retry, or run from a different network.

How this project is funded

By default, amazon.in URLs returned by this server include the author's Amazon Associates tag (artech-21). If you (or your LLM) click through and buy something, the author earns a small commission. You pay the same price. This is the only way the project stays free, MIT, and actively maintained.

Override or disable anytime with the AMAZON_IN_AFFILIATE_TAG env var:

Value	Behavior
unset	Author's tag (`artech-21`) — supports the project
`yourtag-21`	Your own Amazon Associates tag
`none` / `off` / `false` / `""`	No tag, raw amazon.in URLs

Example — your own tag:

{
  "mcpServers": {
    "amazon-in": {
      "command": "node",
      "args": ["/path/to/dist/index.js"],
      "env": { "AMAZON_IN_AFFILIATE_TAG": "yourtag-21" }
    }
  }
}

Roadmap

[ ] Publish to npm so install becomes npx -y amazon-in-mcp-server
[ ] Optional Keepa API support (user-supplied key) for real price-history data
[ ] Filter helpers — min_rating, min_reviews, under_price
[ ] Smoke-test suite with cached HTML fixtures

Development

npm install
npm run dev      # tsx watch
npm run build    # tsc → dist/
npm start        # node dist/index.js

Test interactively with the MCP Inspector:

npx @modelcontextprotocol/inspector node dist/index.js

Project layout:

src/
  index.ts        # MCP server + 3 tool registrations
  scraper.ts      # fetch with UA rotation, retry, bot-check
  parse.ts        # cheerio selectors for search + product pages
  constants.ts    # UAs, headers, tuning constants, affiliate config
  types.ts        # SearchResultItem, ProductDetail

Disclaimer

Fetches publicly accessible amazon.in pages for personal research and assistant use. Does not bypass authentication, paywalls, or CAPTCHAs — when Amazon serves a bot-check the tool stops and reports the error.
