Zinc MCP server

Which MCP servers are Zinc's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Addresshttps://mcp.zinc.com/mcpnot in the official registry: answered when asked

No entry in the official MCP registry names this server. It answered on zinc.com when the Atlas asked at the address servers are usually mounted on, so it is the vendor's own. Clients and catalogues that list servers from the registry do not show it.

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 296 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 2 of the 7 days it takes to judge reliability.

Once connected

  • For "search and compare products across thousands of retailers", the likely first call is search-products.
  • Keep approval on for send_feedback: they delete, send or pay without saying so.
  • send_feedback change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • not sure · place orders programmatically with automatic checkout and payment
  • not sure · track shipments and manage returns across retailer accounts

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that delete, send or pay, marked as not destructive: send_feedback
  • Tools that change data, on a server that answers without a sign-in: send_feedback

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • list-orders

    List or search the Zinc orders on the configured account, newest first. Renders an interactive order list. Use `search` for a partial order ID or tracking number, `status` to filter by order status, and `has_tracking` to show only shipped…

  • get-order

    Fetch one Zinc order by its UUID and render a detail card: line items, retailer price breakdown, shipping destination, and shipment timeline.

  • get-order-tracking

    Return the carrier tracking timeline (scan checkpoints) for one Zinc order. Use this when the question is only about where a package is, not about pricing or line items.

  • list-addresses

    Destinations from the signed-in user's recent orders, each with an id you can pass to prepare-order as address_id. Only useful once the user has signed in (list-orders has worked, or they asked for their history); for anyone else it has…

  • prepare-order

    Show the user an order to review: items, what it will cost and the hold on the card. This does NOT place the order or spend anything — the user places it by clicking Pay & place in the card that appears, and enters their shipping address…

  • place-order

    Internal: places an order the user already confirmed in the review card, paying by card. Requires a confirmation issued by prepare-order, which is not available to you — call prepare-order and let the user confirm instead.

  • get-payment-status

    Where a card payment stands after place-order sent the buyer to a payment page: requires_action until they pay, then placed with the order_id. The review card polls this itself; call it only if the user asks whether their payment went…

  • search-products

    Find products across Amazon, Walmart, Target, Best Buy and more. Each result carries an orderable URL that can be passed straight to prepare-order, along with its title, image and price_cents — pass those too, so the review card can show…

  • send_feedback

    Records feedback about this MCP server, including unexpected tool failures, unhelpful responses, or missing capabilities observed by the agent or reported by the user.

claude.ai, ChatGPT and other clients: add https://mcp.zinc.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
