Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 510 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name zinc.

  • Pass
    Lists tools

    tools/list returned 9 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 510 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 510 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    15 of 28 parameters have a description (54%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-28T07:09:31.451024Z, within 180 days.

  • Not measured
    Open-source licence

Capabilities

Tools 9

get-order

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

Discovered
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.

Discovered
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 through.

Discovered
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 nothing, and the shopper enters the address on the payment page instead. It never prompts for sign-in. Labels are deliberately partial — a name, a city, a truncated postal code. You are not shown the street, and you do not need it: the full address is resolved server-side and shown to the user in the review card before anything is placed. Never reconstruct or guess an address from a label; if none of these is the right destination, ask the user.

Discovered
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 orders.

Discovered
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.

Discovered
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 on the payment page that opens. Use this whenever the user wants to buy something; never ask them for an address first. Pass each product's title, image and price_cents from search so the card shows the item and quotes the total; leave max_price out unless the user named a budget. address_id, from list-addresses, is only for a signed-in user shipping somewhere they have shipped before. Not sold through this connector: weapons, tobacco and nicotine, regulated drugs and paraphernalia, prescription medication, adult products, gambling, covert surveillance and counterfeit goods. An order for one of those is refused.

Discovered
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 the item and quote the total. Use this when the user wants to buy something but has not given a product URL. Then stop and let the user choose from the card — do not go on to prepare-order in the same turn unless they already named the exact item or asked you to pick. Search once with the user's best query rather than issuing speculative variations, and do not retry a failed search without saying why. When the user names the store they want to buy from, pass it in retailers rather than in the query; otherwise leave retailers out and search everywhere. Not sold through this connector: weapons, tobacco and nicotine, regulated drugs and paraphernalia, prescription medication, adult products, gambling, covert surveillance and counterfeit goods. A search for one of those is refused and matching results are dropped; tell the user plainly rather than rephrasing the query to get around it.

Discovered
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.
