## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__store__get_product` |
| 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 `store_policies` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "store_policies" says "store": a word for a change.
```


## Changes things (1)

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

### `store_policies`

- The name "store_policies" says "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Shipping, returns, privacy, terms or contact policy, in full, as published.
```

## Only reads (3)

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

### `get_product`

- The name "get_product" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Everything the product page says about one piece: price, sizes, colour, story and details, the supplier's size chart (garment measurements), delivery estimate, returns, customer reviews and the page to buy it on.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Find pieces in this store by words (e.g. 'wool sweater', 'cardigan', 'rust'), optionally filtered by department, size and maximum price. Empty query lists every piece.
```

### `track_order`

- The description's first verb is "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The status of one order (preparing, shipped, delivered), its items, delivery estimate and tracking. Needs the 8-character order reference from the confirmation email and the email used at checkout.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__store__search_products",
      "mcp__store__get_product",
      "mcp__store__track_order"
    ],
    "ask": [
      "mcp__store__store_policies"
    ],
    "deny": []
  }
}
```

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

- `mcp__store__get_product`: untrusted-input
