## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__www__get-order` `mcp__www__get-order-tracking` `mcp__www__get-payment-status` `mcp__www__list-addresses` `mcp__www__list-orders` `mcp__www__place-order` `mcp__www__prepare-order` `mcp__www__search-products` `mcp__www__send_feedback` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__www__send_feedback` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `place-order`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `send_feedback`

- The name "send_feedback" says "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "send_feedback" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

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

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `get-order`

- The name "get-order" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "get-order-tracking" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `get-payment-status`

- The name "get-payment-status" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `list-addresses`

- The name "list-addresses" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `list-orders`

- The name "list-orders" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `prepare-order`

- The description's first verb is "show": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "show" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search-products`

- The name "search-products" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
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.
```
