## 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__url2ad__create_ad` `mcp__url2ad__request_change` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__url2ad__create_ad` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `create_ad`

- The name "create_ad" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Starts building a free 15-second video ad preview from a public web page, in the language of that page. Use it when the user asks for a video ad for their site, product, app or store. The address must be the user's own, given by them in this conversation: never guess it or use someone else's. It receives the preview link by e-mail. Calling it again with the same page and address returns the same ad.
```

### `request_change`

- The name "request_change" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Rebuilds an existing ad with a change the user asked for, such as other wording, colors or images. It uses up one of the changes left, and one free change is included with a preview, so call it only when the user asked for this change, and pass their request as they said it. The new version takes a few minutes: follow it with get_ad_status.
```

## Only reads (1)

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

### `get_ad_status`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the state of an ad started with create_ad: building, preview_ready, paid, failed or unavailable, with its page link, the changes left and the reason for a failure. Use it when the user asks whether their ad is ready, or before saying that it is. To wait for an ad being built, pass wait_seconds and call again while the status is building.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `url2ad`:

```json
{
  "permissions": {
    "allow": [
      "mcp__url2ad__get_ad_status"
    ],
    "ask": [
      "mcp__url2ad__create_ad",
      "mcp__url2ad__request_change"
    ],
    "deny": []
  }
}
```

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

- `mcp__url2ad__create_ad`: untrusted-input, outbound
- `mcp__url2ad__request_change`: untrusted-input
