kwery MCP server

Live prices, offers and trust scores from Amazon, Google Shopping, Idealo, eBay, Kaufland and more, as tools for your AI assistant. Ask in plain language, for example "Where is GTIN 4006381333962 cheapest in Germany?", and the assistant looks it up on the marketplaces live.

kwery is a hosted remote MCP server. There is nothing to install: point your client at the URL below and send your API key.


Server URL	`https://api.kwery.co/mcp`
Transport	Streamable HTTP
Authentication	Your `kwy_live_` API key in the `x-api-key` header (or `Authorization: Bearer`)
Registry	`co.kwery/mcp` in the official MCP Registry
Full guide	docs.kwery.co/guides/mcp

Get an API key: sign up at kwery.co; the free plan's credits work with MCP too.

Connect

Replace kwy_live_... with your key.

Claude Code

Tools

Tool	Use it for	Cost
`get_product_offers`	One product on one marketplace: price, offers, trust score	The source's credit rate
`compare_prices`	One product on up to 5 marketplaces, ranked by price	The sum of the sources that returned a result
`submit_batch`	Up to 1,000 identifiers on one marketplace as a background job	Estimate first, charged per result
`get_batch_status`	Progress of a batch job	Free
`get_batch_results`	Results of a finished job, paged	Free
`list_sources`	Marketplaces, countries, identifier types and credit rates	Free
`get_account`	Plan, credit balance and credits used	Free

Identifiers: GTIN/EAN, ASIN (Amazon), the marketplace's own product ID, and PZN where supported. Prompts price_check and catalog_sweep and the resource kwery://sources are included.

lowest_price is the cheapest new, in-stock offer including shipping. Every result carries a trust score; below 0.7 means a person should look before acting on it.

Example prompts

"Where is GTIN 4006381333962 cheapest in Germany right now?"
"What does ASIN B08R57HZ4Z cost on Amazon Germany, including shipping?"
"Price these 200 GTINs on Kaufland DE, show me the credit estimate first."
"How many kwery credits do I have left?"

Pricing and limits

MCP calls use the same credits as the kwery API. Cached results and failed lookups are free. Lookups wait up to 50 seconds; if offers are still loading, the assistant gets what has arrived and can fetch the rest later. More in the guide.
