## MCP tools (7)

### `image_info` (~71 tokens)

Image info

Read format, dimensions, alpha and EXIF orientation of a local image file. Call it first when the user asks what an image is, or before picking crop or resize numbers.

Input parameters:

- `input` (string, required): Path to a JPG, PNG, WebP, AVIF, GIF, TIFF or HEIC file.

### `circle_crop` (~197 tokens)

Circle crop

Make a round profile picture: center-square crop plus a circular transparent mask. png (default), webp and avif keep the transparent corners; jpeg flattens them onto a background color. Use when the user wants a round avatar or profile photo (Discord, Slack, LinkedIn, WhatsApp, GitHub) from a local image.

Input parameters:

- `background` (string): CSS color used to flatten transparency when the output is jpeg (default #ffffff).
- `format` (string)
- `input` (string, required)
- `output` (string): Output file path. Default: next to the input, with a suffix and the right extension.
- `preview` (boolean): Attach a small JPEG preview to the result (default true).
- `quality` (integer): Lossy quality 1-100 (default 80). Ignored for png.
- `size` (integer): Output side in pixels (default: the largest centered square).

### `crop_image` (~238 tokens)

Crop image

Crop to a pixel box (left, top, width, height) or to a centered aspect ratio such as 1:1, 4:5 or 16:9. Use when the user wants part of an image or a fixed ratio (square post, 4:5 portrait, 16:9 banner); for a round avatar use circle_crop.

Input parameters:

- `aspect` (string): Centered crop to this ratio, e.g. 16:9. Overrides the pixel box.
- `background` (string): CSS color used to flatten transparency when the output is jpeg (default #ffffff).
- `format` (string)
- `height` (integer)
- `input` (string, required)
- `left` (integer)
- `output` (string): Output file path. Default: next to the input, with a suffix and the right extension.
- `preview` (boolean): Attach a small JPEG preview to the result (default true).
- `quality` (integer): Lossy quality 1-100 (default 80). Ignored for png.
- `top` (integer)
- `width` (integer)

### `resize_image` (~205 tokens)

Resize image

Resize by width, height or percent. Keeps the aspect ratio (fit=inside) and never enlarges unless enlarge=true. Lanczos3 resampling. Use when the user gives target pixel dimensions or wants an image physically smaller or larger; for a lighter file at the same size use compress_image.

Input parameters:

- `background` (string): CSS color used to flatten transparency when the output is jpeg (default #ffffff).
- `enlarge` (boolean)
- `fit` (string)
- `format` (string)
- `height` (integer)
- `input` (string, required)
- `output` (string): Output file path. Default: next to the input, with a suffix and the right extension.
- `percent` (number)
- `preview` (boolean): Attach a small JPEG preview to the result (default true).
- `quality` (integer): Lossy quality 1-100 (default 80). Ignored for png.
- `width` (integer)

### `compress_image` (~142 tokens)

Compress image

Smaller file, same format. jpg/webp/avif re-encode at `quality` (default 80, mozjpeg for jpg); png is recompressed losslessly. Use when the user needs a lighter file (an upload size limit, a faster web page) without changing format or dimensions.

Input parameters:

- `input` (string, required)
- `output` (string): Output file path. Default: next to the input, with a suffix and the right extension.
- `preview` (boolean): Attach a small JPEG preview to the result (default true).
- `quality` (integer): Lossy quality 1-100 (default 80). Ignored for png.

### `convert_image` (~183 tokens)

Convert image

Convert between jpeg, png, webp and avif (the input may also be GIF, TIFF or HEIC). Transparency is kept except for jpeg, which is flattened onto `background`. Use when the user needs another file type, e.g. an iPhone HEIC to JPG, PNG to WebP for the web, or any image to AVIF.

Input parameters:

- `background` (string): CSS color used to flatten transparency when the output is jpeg (default #ffffff).
- `format` (string, required)
- `input` (string, required)
- `output` (string): Output file path. Default: next to the input, with a suffix and the right extension.
- `preview` (boolean): Attach a small JPEG preview to the result (default true).
- `quality` (integer): Lossy quality 1-100 (default 80). Ignored for png.

### `roundcut_web_tools` (~72 tokens)

RoundCut web tools

Links to the RoundCut browser tools for what this server does not do locally: AI background removal, AI upscaling, batch conversion and image-to-PDF. Free, 29 languages. Call it when the user asks for one of those, so you can point to a working tool instead of declining.
