## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__spywinads__spywin_export_shopify_product` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__spywinads__spywin_export_shopify_product` |

## Findings

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

```untrusted-server-text
The server marks "spywin_spy_store_ads" 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 "spywin_spy_store_ads" says "store": a word for a change.
```


## Changes things (1)

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

### `spywin_spy_store_ads`

- The name "spywin_spy_store_ads" 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
See the Facebook video ads a Shopify / online store is running. Input: the store domain. Returns live ads, new ads in 7 days, number of videos, products and Pages, and the top videos with their real age and how many stores run each one.
```

## Only reads (4)

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

### `spywin_export_shopify_product`

- The description's first verb is "read": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read a public Shopify product page and return its title, prices, variants and images, plus a download link to a Shopify-import CSV (valid 24 hours) and the product's video ads if the SpyWinAds library has them.
```

### `spywin_get_page_ads`

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

Description, as the server wrote it:

```untrusted-server-text
See the video ads a Facebook Page runs: total and live ads, videos, top videos with real age, and the stores the Page sends traffic to. Input: Facebook Page link or Page ID.
```

### `spywin_get_video_reuse_research`

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

Description, as the server wrote it:

```untrusted-server-text
Headline numbers from SpyWinAds Research 'Video Reuse Index': how often Facebook video ads are old videos brought back, how many stores share a video, and how fast a video spreads to 5 stores. With method link.
```

### `spywin_lookup_video_ad`

- The name "spywin_lookup_video_ad" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check how old a Facebook video ad really is and which stores run the same video. Input: a Meta Ad Library link or ad ID. Returns the day the video file was first uploaded to Facebook (accurate to 1-2 days), the first ad date, live ads, how many stores run the same video now and ever, and the earliest stores in the SpyWinAds library.
```

## Claude Code permissions

      "mcp__spywinads__spywin_export_shopify_product"
    ],
    "deny": []
  }
}
```
