## 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__image-tools__process_images` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__image-tools__process_images` |

## 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_upload`

- The name "create_upload" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Get a one-hour signed upload URL for an image or a zip that is too large to send inline (over 3 MB; up to 100 MB here) or that already sits on disk. PUT the raw bytes to upload_url with a Content-Length header, then pass file_id to process_images. Free.
```

### `process_images`

- The description's first verb is "resize": 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
Resize, crop, rotate, flip, compress (to a file size with target_bytes), convert (jpeg, png, webp, avif), strip EXIF and GPS metadata from, and watermark (text, logo or both) one image or a zip of up to 50 images (up to 500 files per zip; files that are not supported images are skipped and listed). Crops are in pixels by default; for a zip of different sizes use crop_unit "percent" or crop_aspect, which are worked out per image. Give exactly one source: file_id (from create_upload), url (public https) or data_base64 (up to 3 MB inline; use create_upload, up to 100 MB, or url above that). One image in returns one image; a zip returns a zip. AVIF output is scaled down to fit 1,200 px on the longest side and WebP output to 36 megapixels. Returns a 24-hour download_url with the size and format of every output, and for each output the kinds of metadata found in the input and left in the output (location, date, camera, serial number, ...) and whether the colour profile was kept; kinds only, never the values. keep_date and keep_copyright write back the EXIF date taken and copyright after stripping. Large zips can take up to a minute; use a client timeout of at least 120 s. Free. Daily quotas are counted per caller in output megapixels; see start.md.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `image-tools`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__image-tools__process_images",
      "mcp__image-tools__create_upload"
    ],
    "deny": []
  }
}
```

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