## 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__shop__get_size_guide` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__shop__get_cart` |
| 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 `remove_line` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "remove_line" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":false}; The name "remove_line" says "remove": a word for removing or ending something.
```


## Deletes or cancels (1)

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

### `remove_line`

- The name "remove_line" says "remove": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict

```untrusted-server-text
Removes a line from the cart.

### `create_cart`

- The name "create_cart" says "create": a word for a change.

Description, as the server wrote it:

Creates an empty cart. Returns cart_token (keep it for the other cart tools) and checkout_url (give it to the person: they finish and pay on macron.lt).
```

### `set_quantity`

- The name "set_quantity" says "set": a word for a change.

```

Find products by name, model or type (Lithuanian or model names work best, e.g. "marškinėliai", "kojinės", "MAIA"). Returns up to 20 products that can be ordered now.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__shop__search_catalogue",
      "mcp__shop__get_product",
      "mcp__shop__get_availability",
      "mcp__shop__get_size_guide",
      "mcp__shop__get_cart"
    ],
    "ask": [
      "mcp__shop__create_cart",
      "mcp__shop__add_line",
      "mcp__shop__set_quantity"
    ],
    "deny": [
      "mcp__shop__remove_line"
    ]
  }
}
```

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

- `mcp__shop__get_size_guide`: private-data
- `mcp__shop__get_cart`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:10:14.623Z, unchanged since 2026-10-22T15:10:14.623Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

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

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (1 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://macron.lt/mcp: tools/list returned 9 tools to an anonymous client, including remove_line (destructive), create_cart (write), add_line (write), set_quantity (write)
```
