## 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__luala__add_photo` `mcp__luala__add_selfie` |
| 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 `remove_background` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "remove_background" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "remove_background" says "remove": a word for removing or ending something.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "upload_status" says "upload": a word for a change.
```


## Deletes or cancels (1)

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

### `remove_background`

- The name "remove_background" says "remove": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Cuts the person out of one of the user's photos, paid from their credits: on a clear (transparent) backdrop unless backdrop names a colour, #rrggbb (the app offers #ffffff, #e9e7e3, #3a3a3c, #000000, #1f2f4d, #bcd7ee, #f2e8d5, #b9c8b0). On a photo that is already a cutout it lays it on another backdrop. Pass the price the user agreed to as max_credits: the photo's prices from get_shoot or list_photos name it. If a call to this tool got no answer, it may already have started: check list_photos before calling it again.
```

## Changes things (14)

Description, as the server wrote it:

```untrusted-server-text
Adds one photo to the user's My photos in Luala, free, so it can be edited: an old print to restore, clothes to try on, a photo to change. The answer is the saved photo with its photo_id and edit prices: when the user asked for an edit of it, tell them that edit's price, and once they agree make it with Luala's tool for it on this photo_id, never with another image tool. Pass the file the user attached as photo. If you can't, but the file is in your sandbox, call with its content_type (image/jpeg, image/png or image/webp: convert a HEIC to JPEG first) and size in bytes, PUT the file to the answer's upload url with its headers, then call again with the answer's key. Called with none of these, it answers with the luala.app page where the user adds it. The user accepted the upload rules when connecting Luala.
```

### `add_selfie`

- The name "add_selfie" says "add": a word for a change.
