## 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

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `cancel_order`

- The name "cancel_order" says "cancel": a word for removing or ending something.
- The description says "cannot be undone".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel an order that has not shipped. This cannot be undone. Call it first with confirm=false to get the order details, show them to the user, and only after the user explicitly agrees call again with confirm=true.
```

## Changes things (1)

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

### `create_order`

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

Description, as the server wrote it:

```untrusted-server-text
Place an order for one product. Generate one random idempotencyKey per user request and reuse the same key if you retry after an error or timeout; the shop returns the original order instead of creating a duplicate. Confirm product and quantity with the user before calling. Returns the order with its id, status and total.
```

## Only reads (2)

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

### `get_product`

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

Description, as the server wrote it:

```untrusted-server-text
Return the full details of one product by its id (for example p-1001). Use search_products first if you only know a name.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search the shop catalogue by phrase and optional category. Returns one page of up to `limit` products and a `nextCursor`; when nextCursor is not null, more results exist and you must say so rather than claiming the list is complete. Use get_product for full details of one item. This tool does not place orders.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__sample-shop__search_products",
      "mcp__sample-shop__get_product"
    ],
    "ask": [
      "mcp__sample-shop__create_order"
    ],
    "deny": [
      "mcp__sample-shop__cancel_order"
    ]
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:56:22.850Z, unchanged since 2026-10-22T14:56:22.850Z. 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 | `2` |
| 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 2 tools that change things (1 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://demo.apitoagents.com/mcp: tools/list returned 4 tools to an anonymous client, including cancel_order (destructive), create_order (write)
