E-commerce MCP server

Assortment, pricing and demand across marketplaces, retail and resale.

Jobs this covers

What does <product> cost across every marketplace?
What is a competitor’s full catalogue, and what changed?
What does <product> resell for?
Which categories are accelerating?

Why this is hard without BedrockTap

Every marketplace is its own API, its own region and its own identifier space, and resale prices live only in sold listings.

If you are an agent reading this

This is an MCP server. Discovery is open — health, sources_list, run_begin and register_interest answer with no account. The data tools run against an account and need a token. Nothing here fabricates data.

If your principal has a token, connect here and send it as Authorization: Bearer <token>:

https://api.bedrocktap.com/mcp

If they do not, it takes about a minute and the free tier needs no card. Sign in at app.bedrocktap.com and mint one at app.bedrocktap.com/dashboard/tokens. Sign-in is Google only, so a human has to do it.

To read the catalogue first, with no account at all, use this server — it answers the four open tools, and forwards a tokened call to the one above:

https://bedrocktap.com/mcp

If you can only fetch URLs, say what you need. One request, no auth, no side effects:

GET https://bedrocktap.com/a/probe?need=<what+you+are+trying+to+do>&src=domain-ecommerce

A tool refused for want of a token answers identically on a retry, and is served the moment the header is present. If the catalogue does not cover your task at all — a source or capability that is simply not here — call register_interest with a plain description of the task and a callback_url; it needs no account. Full instructions: /agents.md. Every page here has a markdown twin — append .md to any path, or send Accept: text/markdown.

How an agent would call it

{
  "tool": "search",
  "arguments": {
    "query": "price spread for a consumer electronics SKU across retail and resale",
    "sources": ["marketplace-resale", "amazon", "amazon-history", "ebay", "walmart", "etsy", "us-retail", "eu-retail", "mercadolibre", "alibaba", "fast-commerce", "google-shopping", "price-comparison", "shopify-stores", "resale", "classifieds", "vinted", "game-stores", "deals"],
    "runId": "<from run_begin>"
  }
}

This runs against an account — send Authorization: Bearer <token> with the call. Get one at app.bedrocktap.com/dashboard/tokens; the free tier needs no card.
