## 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__fortsu__get_product` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

## Only reads (3)

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

### `get_min_price_history`

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

Description, as the server wrote it:

```untrusted-server-text
Minimum price history of a product, newest first.
```

### `get_product`

- The name "get_product" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

### `search_products`

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fortsu__search_products",
      "mcp__fortsu__get_product",
      "mcp__fortsu__get_min_price_history"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__fortsu__get_product`: untrusted-input
