## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__printful__printful_get_file` `mcp__printful__printful_get_printfiles` `mcp__printful__printful_get_store_product` `mcp__printful__printful_get_sync_product` `mcp__printful__printful_list_catalog_products` |
| 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. | `mcp__printful__printful_calculate_shipping_rates` `mcp__printful__printful_estimate_order_costs` |

## Findings

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

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

annotations: {"readOnlyHint":true}; The input addresses people (input.recipient): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true}; The input addresses people (input.recipient): what it sends cannot be taken back.
```


## Deletes or cancels (4)

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

### `printful_add_file`

- The name "printful_add_file" says "add": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Add a print file to the File Library from a public URL (PNG/JPG recommended). If a file with the same URL already exists it is returned instead. Processing is async — poll printful_get_file until status is ok. Printful: POST /files.
```

### `printful_create_draft_order`

- The name "printful_create_draft_order" says "create": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Create an order as a DRAFT — nothing is charged or produced. It must be confirmed later in the Printful dashboard, where the charge is shown. Each item needs one of variant_id (+ files), sync_variant_id, external_variant_id, warehouse_product_variant_id or product_template_id (+ variant_id). Printful: POST /orders (never with confirm).
```

### `printful_create_mockup_task`

- The name "printful_create_mockup_task" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Start generating product mockups for a design on a catalog product — returns a task_key; poll printful_get_mockup_task for the images. Heavily rate-limited (about 10/min for established stores, 2/min for new ones). Printful: POST /mockup-generator/create-task/{id}.
```

### `printful_update_draft_order`

- The name "printful_update_draft_order" says "update": a word for a change.
- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Change a DRAFT order (unsubmitted orders only) — send only the fields to change. CAUTION: if you send `items`, it replaces the list: existing items not included (by id or external_id) are removed. The order stays a draft; nothing is charged. Printful: PUT /orders/{id} (never with confirm).
```

## Can't be undone (2)

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

### `printful_calculate_shipping_rates`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Quote the shipping options (method id, name, rate, delivery-day estimate) for a set of items to an address. Only country_code is required (plus state_code for US/CA/AU). Changes nothing. Printful: POST /shipping/rates.
```

### `printful_estimate_order_costs`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Price an order WITHOUT creating it: item, print, shipping and tax costs, plus retail totals. Same item shape as printful_create_draft_order. Changes nothing. Printful: POST /orders/estimate-costs.
```

## Only reads (15)

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

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (4 destructive, 2 irreversible). Whether a call also works without credentials was not tested: tools are never called.

https://printful.usefulapi.io/mcp: tools/list returned 21 tools to an anonymous client, including printful_create_draft_order (destructive), printful_update_draft_order (destructive), printful_add_file (destructive), printful_create_mockup_task (destructive), printful_calculate_shipping_rates (irreversible) and 1 more
