## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__shippit__shippit_get_manifest_document` `mcp__shippit__shippit_get_merchant` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__shippit__shippit_book_orders` `mcp__shippit__shippit_cancel_order` `mcp__shippit__shippit_create_order` `mcp__shippit__shippit_estimate_delivery_dates` `mcp__shippit__shippit_get_manifest_document` `mcp__shippit__shippit_get_merchant` `mcp__shippit__shippit_get_operating_hours` `mcp__shippit__shippit_get_order` `mcp__shippit__shippit_get_quotes` `mcp__shippit__shippit_get_tracking` `mcp__shippit__shippit_label_order` `mcp__shippit__shippit_list_webhooks` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "shippit_get_operating_hours" says "get": a word for reading.
```


## Deletes or cancels (3)

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

### `shippit_book_orders`

- The description's first verb is "write": a word for a change.
- 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
WRITE: book labelled orders with their carriers for pickup (the Shippit 'book' step). Shippit returns one manifest per carrier; the carrier then collects and bills the parcels. Orders must have been labelled first (shippit_label_order). The call fails as a whole when a tracking number is unknown; otherwise each manifest reports success or an error per order. Booked orders can no longer be edited. Requires confirm: true. A reply where every manifest failed is an error. POST /book.
```

### `shippit_cancel_order`

- The name "shippit_cancel_order" says "cancel": a word for removing or ending something.
- 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
WRITE: cancel a Shippit order by tracking number (the order ends in state cancelled and cannot be revived; for some carriers Shippit also sends a cancellation request to the carrier). Shippit refuses with a 422 and the reason when the order can no longer be cancelled, for example once the carrier has it. Requires confirm: true. DELETE /orders/{tracking_number}.
```

### `shippit_create_order`

- The name "shippit_create_order" says "create": a word for a change.
- 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
WRITE: create a domestic shipping order in Shippit. Shippit then allocates a carrier (your account rules, or the carrier named in courier_allocation) and, unless suppress_communications is true, emails the recipient tracking notifications. Requires confirm: true. Standard, express and click-and-collect orders are only booked with the carrier later, by shippit_label_order and shippit_book_orders (priority and on-demand orders, which book inside the create request, are not supported here). validate defaults to true: the order is not saved when the suburb and postcode do not match (a suggested address is returned instead). Creating twice creates two orders. International orders (customs data) are not supported here. POST /orders.
```

## Changes things (3)

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

### `shippit_estimate_delivery_dates`

- 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.
- 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
Estimated delivery window (earliest, latest, confidence and a ready-to-show text) per service level (standard, express) between two postcodes, optionally limited to some carriers. Returns an empty list if no carrier is enabled. POST /estimated_delivery_dates.
```

### `shippit_get_operating_hours`

- The name "shippit_get_operating_hours" says "get": a word for reading.
- The description's first verb is "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The store operating hours per weekday (open flag, start and end of the working day) that Shippit uses for pickup and delivery estimates. GET /merchants/settings/locations/operating_hours.
```

### `shippit_label_order`

- The name "shippit_label_order" says "label": 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
WRITE: confirm an order for shipping and fetch its label. This is the Shippit 'label' step: it finalises the carrier and price (the order moves to Ready to Ship) and returns the carrier, tracking and consignment details plus pre-signed PDF URLs (valid 7 days) for the shipping label, packing slip and any customs documents. A 422 means the order is still processing or has no valid carrier or quote: retry shortly or read the error. Labelling is the step before shippit_book_orders. GET /orders/{tracking_number}/label.
```

## Only reads (6)

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

### `shippit_get_manifest_document`

- The name "shippit_get_manifest_document" says "get": a word for reading.
- Tag private-data: The name "shippit_get_manifest_document" says "get" and "document": it reads documents. The description's first sentence says "document": it reads documents.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The booking manifest document for a manifest id (from shippit_book_orders or shippit_get_order): carrier, order count, tracking numbers and a pre-signed PDF URL valid for 7 days. A 422 means the manifest is still generating: retry shortly. GET /book/{manifest_id}/document.
```

Set return_all_quotes to see every carrier instead of only the cheapest or fastest. A 200 can hold per-carrier errors (success false) and a quote of 0 means that carrier cannot take the parcel. Dangerous goods cannot be quoted. POST /quotes.
```

### `shippit_get_tracking`

- The name "shippit_get_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. The description's first sentence says "status" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The status history of an order (status, date, time, who changed it) and the public tracking page URL to give the recipient. GET /orders/{tracking_number}/tracking.
```
