Pricing intelligence MCP server

What things actually sell for, across retail and resale, now and over time.

Jobs this covers

What does <product> sell for, new and used, right now?
How has <product>’s price and rank moved over the last year?
Did <competitor> change their pricing page, and what changed?
What is the spread between marketplaces for the same item?

Why this is hard without BedrockTap

Retail pricing is per-marketplace and per-region, resale prices are only in sold listings, and history exists nowhere unless someone recorded it.

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-pricing-intelligence

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": "new and resale price spread for a discontinued mechanical keyboard",
    "sources": ["amazon", "amazon-history", "ebay", "walmart", "vinted", "shopify-apps", "page-diff", "pricing-pages", "price-comparison", "google-shopping", "deals", "us-retail", "eu-retail", "mercadolibre", "alibaba", "fast-commerce", "etsy", "resale", "classifieds", "game-stores", "marketplace-resale", "shopify-stores"],
    "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.
