## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `create_cart_url` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_cart_url" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_cart_url" says "create": a word for a change.
```


## Changes things (1)

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

### `create_cart_url`

- The name "create_cart_url" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Create a checkout link on packrift.com for items the buyer has chosen. Give each item as SKU and quantity (number of packs); up to 25 lines. The link opens packrift.com checkout with those items and automatic volume discounts applied; the buyer adds their address and pays there. Returns the subtotal after volume discounts. This tool never places an order or charges anyone. Call it only after the buyer confirms the items and quantities.
```

## Only reads (5)

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

### `find_packaging_for_item`

- The name "find_packaging_for_item" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the right Packrift box or mailer for an item the buyer ships. Give the item's length, width and height in inches, its weight, and what it is (for example "ceramic mug", "t-shirt", "hardcover book", "laptop"). Applies cushioning space by item type (2 in per side for fragile items), checks box strength against the weight, and compares billable shipping weight (UPS/FedEx and USPS dimensional weight). Returns up to 5 in-stock options with inside size, fit, strength, live price and a product link. Use search_products instead when the buyer already knows the packaging size they want.
```

### `get_bulk_quote_link`

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

Description, as the server wrote it:

```untrusted-server-text
Get a pre-filled quote request link for pallet or recurring quantities, custom sizes, printed or branded packaging, freight orders, or any spec Packrift does not stock exactly. Put everything the buyer told you in the fields: the spec, quantity, delivery ZIP and need-by date travel with the request. The buyer adds their email and submits the form on packrift.com; Packrift replies by email with pricing. Returns the link and what the buyer still needs to add.
```

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Get one Packrift product by SKU (or product handle): specs such as inside size, material, strength and pack count, live price and price per unit, stock, whether a quantity can ship now, volume pricing, nearby sizes and the product link. Use after search_products or find_packaging_for_item when the buyer wants more detail before choosing.
```

### `get_shipping_estimate`

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

Description, as the server wrote it:

```untrusted-server-text
Estimate the delivered cost of a Packrift order to a US ZIP code, using the same shipping rates and automatic volume discounts as Packrift checkout. Give the items as SKU and quantity (number of packs). Returns the subtotal after discounts, the shipping charge (free only when the order qualifies), the delivered total and the delivered cost per unit. Tax is not included; checkout shows the final amount. Not for carrier rate shopping or postage.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search Packrift's in-stock packaging catalog: corrugated shipping boxes, mailer boxes, poly and bubble mailers, poly bags, labels, packing tape, stretch film and void fill. The query can be a product type, an exact size or spec ("12x12x12 ECT-32 box", "10x13 poly mailer", "3 inch packing tape"), or a Packrift SKU. Returns up to 10 matches with live price, pack size, price per unit, stock and a product link. A different size is never labeled exact; when nothing matches exactly it returns the closest sizes marked as not exact and a quote link. If the buyer describes the item they are shipping rather than the packaging they want, use find_packaging_for_item instead.
```

## Claude Code permissions

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
