Agentic Product Protocol MCP Server

Klarna-style product discovery for AI shopping agents.

Makes product catalogs machine-readable so AI agents can search, compare, and purchase products programmatically — no screen scraping, no landing pages.

The Problem

Today's e-commerce is built for humans: landing pages, image carousels, "Add to Cart" buttons. AI shopping agents can't efficiently navigate this. They need structured product data — not HTML.

Klarna introduced the Agentic Product Protocol (December 2025) to solve exactly this: a standardized way for merchants to expose their product catalogs to AI agents. Think of it as RSS feeds, but for shopping.

What This Server Does

This MCP server implements the core ideas of agentic product discovery:

• Structured search results — not web pages, but clean JSON with name, price, nutrition, ratings
• Product comparison — side-by-side structured comparison across multiple dimensions
• Feed conversion — take any product feed (JSON, CSV, Open Food Facts) and normalize it into an agent-friendly schema
• Schema generation — convert raw product data into the Agentic Product Protocol format
• Availability checking — real-time product status in a machine-readable format

Uses Open Food Facts as a demo data source — works with any product feed.

Installation

pip install agentic-product-protocol-mcp

Or with uvx (no install needed):

Tools

Example Usage

Search for products:

"Search for organic chocolate bars"

Compare products:

"Compare these three chocolate bars: 3017620422003, 7622210449283, 7613034626844"

Convert a feed:

"Convert this Open Food Facts search into agent-friendly format: https://world.openfoodfacts.org/cgi/search.pl?search_terms=protein+bar&page_size=10"

Generate schema:

"Generate an agentic product schema for this product data: {name: 'Widget Pro', price: 29.99, category: 'Electronics'}"

Why Structured Feeds > Landing Pages

Data Source

This server uses Open Food Facts as its demo data source — a free, open, community-built database of food products from around the world. No API key required.

For production use, connect your own product feeds using the convert_feed tool with JSON or CSV format.
