cartpie

Plug Cartpie into any AI agent.

The Cartpie MCP server gives Claude, Cursor, Windsurf and every other MCP-compatible client native tools for product extraction — one URL in, structured JSON out. Without writing a fetch call.

Three tools for retailer product data.

  • extract_product(url: string)

    Turn a product URL from a supported retailer into a normalized JSON object — title, price, currency, availability, variants, GTIN.

  • extract_products(urls: string[])

    Batch extraction. The agent passes an array of URLs; the server fans out and streams structured results back.

  • find_offers(gtin: string)

    Cross-retailer offer lookup by identifier. Compare prices and availability across the retailers we support.

Wire it into your client in 30 seconds.

Add a single block to your MCP client's config. Restart. Cartpie shows up in the tool palette — no rebuild, no deploy.

The shortest path from your agent to the shelf.

Agent-native

No REST glue, no parsing, no schemas to maintain in the prompt — tools and arguments are typed at the protocol level.

Zero install

One npx line. The server runs on the user's machine and talks to Cartpie over HTTPS — no extra infra to deploy.

Same key. Same credits.

MCP calls bill against the same monthly credits as /v1. Cache hits and failures stay free, same as the REST API.

Give your agent a cart.

100 free credits to start. Same key works for REST and MCP.
