## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `delete_image`

- The name "delete_image" says "delete": a word for removing or ending something.
- The description says "Permanently delete".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Permanently delete one PixelVault image by id. Maps to DELETE /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
```

## Changes things (5)

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

### `rescue_imgur`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Scan a web page for hotlinked Imgur images and return a PixelVault rescue URL for each — a proxy that lazily rehosts the image on first request, keeping it working through the UK Imgur block. The anonymous rescue tier is a durable ~30-day edge cache (see `cache_ttl_days` in the result), not permanent storage. Maps to POST /v1/imgur-scan (server-side page fetch; no API key required). Provide `page_url` (a public https:// page). Drop each returned rescue_url into your HTML to rehost on first request.
```

### `sign_url`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Mint a time-limited signed URL for a private image. Maps to POST /v1/images/:id/sign-url. Provide `id` and optional `expires_in` (seconds, default 3600). The signature binds the image, so the URL can't be replayed against another image; strip it and the CDN returns 403. Deleting the image revokes its URLs. Requires a PixelVault API key sent as a Bearer token in the Authorization header.
```

### `transform_image`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Build an on-the-fly transform URL for a PixelVault image (resize, crop, format/quality, AI background removal, blur/sharpen/rotate/flip, brightness/contrast/saturation, and same-project watermark tiling). Provide exactly one of `url` (a PixelVault CDN URL) or `id` (an image id, resolved via the API — requires an API key), plus one or more transform params. Returns the ready-to-use CDN URL; the transform is produced and cached on first request. See https://pixelvault.dev/docs#transforms.
```

### `upload_batch`

- The name "upload_batch" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Upload many images (1–50) in one call, grouped into a collection — e.g. a CI run or a set of generated variants. Maps to POST /v1/images/batch. Each item is `data` (base64) or `source_url` (server-fetched, SSRF-guarded), with optional `filename`/`metadata`. Set `visibility: "private"` to get a signed URL per image (free plan: up to 100 private images) instead of a public CDN URL. Optional `type`/`name` (idempotent by (type, name)), `expires_in` (image TTL), `sign_expires_in` (signature lifetime), and collection `metadata`. Partial-failure tolerant: each returned item has its own `ok`. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
```

### `upload_image`

- The name "upload_image" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Upload an image to PixelVault and get an instant CDN URL. Maps to POST /v1/images. Provide exactly one of `source_url` (a public http(s) URL the server fetches) or `data` (base64-encoded bytes); optional `folder`, `filename`, and `expires_in` (seconds, for an auto-expiring image). Max 5 MB; JPG/PNG/GIF/WebP/AVIF/SVG. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
```

## Only reads (2)

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

### `get_image`

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

Description, as the server wrote it:

```untrusted-server-text
Get metadata (CDN URL, size, MIME type, dimensions) for one PixelVault image by id. Maps to GET /v1/images/:id. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
```

### `list_images`

- The name "list_images" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List images in your PixelVault project, most recent first. Maps to GET /v1/images with pagination. Requires a PixelVault API key sent as a Bearer token in the Authorization header. The returned CDN URL supports on-the-fly transforms via query params — e.g. ?w=400&fit=cover (resize/crop), ?fmt=webp (format), ?segment=foreground (AI background removal → transparent PNG), effects like ?blur=30&saturation=0&rotate=90, and ?tile=<image_id.ext> (tile another of your images as a watermark). Or call the transform_image tool to build a valid transform URL for you. See https://pixelvault.dev/docs#transforms.
