## 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__shop__get_shipping_estimate` `mcp__shop__request_quote` `mcp__shop__start_checkout` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__shop__request_quote` |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_price_and_stock`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Price and stock for a list of items, the subtotal, and whether the order can be bought online now (published prices, under the card limit) or needs a quote.
```

### `request_quote`

- The name "request_quote" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Ask Arctic White for a quote (any items, including those priced on request, large orders, POs or net terms). We email the buyer a link to confirm the request; once confirmed, our team replies with pricing and lead times, usually within 24 hours.
```

### `start_checkout`

- The name "start_checkout" says "start": a word for a change.
- 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
Create a secure Stripe checkout link on arcticsci.com for items with published prices. The buyer opens the link to review the order, see sales tax and pay; nothing is charged until they do. Use the shipping option id from get_shipping_estimate, or leave it out for the lowest rate. Items priced on request, or orders over the card limit, need request_quote instead.
```

## Only reads (3)

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

### `get_product`

- The name "get_product" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full details for one product: description, specifications and dimensions, options with SKU, price and stock, image and page link.
```

### `get_shipping_estimate`

- The name "get_shipping_estimate" 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
Live FedEx shipping options and prices for the items to an address, the same rates checkout charges.
```

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search Arctic White's catalog of lab consumables (microplates, deep well plates, reservoirs, sealing mats and films, tubes, filter plates, lab equipment) by catalog number, a competitor's part number, name, well count or type. Returns SKUs, published prices (or 'pricing on request'), stock and product links.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `shop`:

```json
{
  "permissions": {
    "allow": [
      "mcp__shop__search_products",
      "mcp__shop__get_product",
      "mcp__shop__get_shipping_estimate"
    ],
    "ask": [
      "mcp__shop__check_price_and_stock",
      "mcp__shop__start_checkout",
      "mcp__shop__request_quote"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__shop__get_shipping_estimate`: untrusted-input
- `mcp__shop__start_checkout`: untrusted-input
- `mcp__shop__request_quote`: untrusted-input, outbound
