## 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__shipnote__list_card_designs` |
| 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__shipnote__create_draft` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `create_draft`

- The name "create_draft" says "create": a word for a change.
- The input addresses people (input.recipients): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.recipients): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Save a DRAFT of postcards, from a single card to one person (e.g. "send a thank-you postcard to my aunt") to a whole registry or guest list, and return a link where the sender adds their return address, reviews every card, and pays on shipnote.co. This tool never mails a card and never charges anyone. Each recipient is one card (one per household for a list): the name as it appears on the card, the full US mailing address as "Street, City, ST ZIP" (empty if unknown), and the gift as a short noun phrase without the store name (e.g. "stand mixer", not "KitchenAid stand mixer from Target"). senderName is the name the sender signs cards with; without it, the default message stays unsigned until the sender fills it in on shipnote.co. Up to 500 recipients per draft. Each call makes a new draft with a new link. This tool can't take a picture. A photo card (the sender's own picture as the whole front) is saved with design image-only, and the sender adds the photo on shipnote.co after opening the link; a photo inside a design uses a design marked (1 photo). list_card_designs also shows designs that need no photo.
```

## Changes things (1)

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

### `quote_price`

- 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 for printing, stamping and mailing a number of ShipNote postcards within the US. Read-only: it saves nothing and charges nothing.
```

## Only reads (1)

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

### `list_card_designs`

- The name "list_card_designs" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "note": it reads notes.

Description, as the server wrote it:

```untrusted-server-text
List the occasions ShipNote makes postcards for, and the card designs available for one occasion, each with the id that create_draft accepts as design. Read-only: it saves nothing.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__shipnote__list_card_designs"
    ],
    "ask": [
      "mcp__shipnote__quote_price",
      "mcp__shipnote__create_draft"
    ],
    "deny": []
  }
}
```

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

- `mcp__shipnote__list_card_designs`: private-data
- `mcp__shipnote__create_draft`: outbound
