amazon-in-mcp-server

amazon-in-mcp

An MCP 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, page=1)	Ranked listings + two convenience picks: cheapest in stock and best value (rating × log10(reviews) / √price). page fetches deeper result pages.
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",
  "page": 1,
  "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

Claude Code

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

Claude Desktop

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

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

Cursor / Windsurf / others

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

Configuration

All optional. Set these in the env block of your MCP client config; defaults preserve the original behavior.

Env var	Default	Purpose
AMAZON_IN_AFFILIATE_TAG	artech-21	Amazon Associates tag on emitted URLs. none / off / "" disables. See funding.
AMAZON_IN_CACHE_TTL_MS	90000	Lifetime of the in-memory page cache (ms). 0 disables caching.
AMAZON_IN_PROXY	unset	HTTP/HTTPS proxy URL for all requests, e.g. http://user:pass@host:8080.

Example — route through a proxy and shorten the cache to 30 s:

{
  "mcpServers": {
    "amazon-in": {
      "command": "node",
      "args": ["/path/to/dist/index.js"],
      "env": {
        "AMAZON_IN_PROXY": "http://user:[e-mail]:8080",
        "AMAZON_IN_CACHE_TTL_MS": "30000"
      }
    }
  }
}

Automatic routing (no need to say "use the Amazon MCP")

Once installed, the server tells your client to reach for these tools on its own. It ships MCP server instructions (returned in the initialize handshake) that instruct the model to use search_amazon_in / get_product by default for any amazon.in shopping, price, availability, or reviews question — including when you just paste an amazon.in link or an ASIN. The tool descriptions carry the same trigger keywords as a fallback for clients that read tool descriptions but not server instructions.

So you can ask "find me a mechanical keyboard under 3000" or paste a product link and the client routes to this server without you naming it. Note this is model-level guidance surfaced by the host (Claude Code, Claude Desktop, Cursor, …), not a hard protocol guarantee — a client that ignores server instructions and tool descriptions won't be forced to route.

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
Caching	Successful pages cached in memory for 90 s (per URL) to skip duplicate fetches; tune with AMAZON_IN_CACHE_TTL_MS, 0 disables
Proxy	Optional — set AMAZON_IN_PROXY to route requests through an HTTP/HTTPS proxy when a datacenter IP is blocked
State	None persisted. Stdio, no cookies, no session — the cache is a short-lived, in-process buffer only

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

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, proxy, cache
  parse.ts        # cheerio selectors for search + product pages
  cache.ts        # in-memory TTL + LRU cache
  constants.ts    # UAs, headers, tuning constants, affiliate/proxy/cache 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.
