## 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__gift-up__giftup_get_order` `mcp__gift-up__giftup_list_orders` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__gift-up__giftup_get_company` `mcp__gift-up__giftup_get_gift_card` `mcp__gift-up__giftup_get_item` `mcp__gift-up__giftup_get_item_group` `mcp__gift-up__giftup_get_order` `mcp__gift-up__giftup_get_transaction` `mcp__gift-up__giftup_list_gift_cards` `mcp__gift-up__giftup_list_item_groups` `mcp__gift-up__giftup_list_items` `mcp__gift-up__giftup_list_locations` `mcp__gift-up__giftup_list_orders` `mcp__gift-up__giftup_list_promotions` `mcp__gift-up__giftup_list_transactions` |

## Findings

- **warn** Annotations that disagree with the tool in `giftup_get_gift_card` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "giftup_get_gift_card" says "get": a word for reading.
```

- **warn** Annotations that disagree with the tool in `giftup_list_transactions` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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