Overview

AI-generated overview

Remote MCP server that gives an assistant real-time product data across 450+ retailers, including prices, images, availability and margin estimates by UPC.

What you can do
Look up a product by UPC for title, brand, description, images and prices at every retailer, or search retailer catalogs by keyword, brand or category. Compare current prices across retailers and review historical price changes over time. Check in-stock status at one or all retailers and pull deduplicated product images from every source. Find high-margin deals between source cost and marketplace sell price, and list recently discovered products.
When to use it
Useful for price comparison, AI shopping assistants, retail arbitrage and product sourcing, MAP monitoring, new product drop alerts, and catalog enrichment with images, descriptions and specs.
Requirements
A remote streamable HTTP endpoint; no local package. A bearer API key sent in the Authorization header, obtained by email signup. The free tier allows 500 lookups per month without a credit card; paid tiers raise the limit.
Before you install
The API key is a secret sent in the Authorization header and should be kept private. Lookups are metered, and paid tiers cost money per month, so usage can incur charges. The README mentions a coming marketplace listing feature at 15% commission.

Installation

In SourceWeft

  1. Open Product Source in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.productsource%2Fproduct-source/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
