The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
circle_crop Circle crop ~197
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.
| Name | Type | Req | Description |
|---|---|---|---|
| background | string | – | CSS color used to flatten transparency when the output is jpeg (default #ffffff). |
| format | string | – | – |
| input | string | yes | – |
| 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). |
No output schema declared.
No examples provided.
compress_image Compress image ~142
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.
| Name | Type | Req | Description |
|---|---|---|---|
| input | string | yes | – |
| 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. |
No output schema declared.
No examples provided.
convert_image Convert image ~183
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.
| Name | Type | Req | Description |
|---|---|---|---|
| background | string | – | CSS color used to flatten transparency when the output is jpeg (default #ffffff). |
| format | string | yes | – |
| input | string | yes | – |
| output | string | – | Output file path. Default: next to the input, with a suffix and the right extension. |

No output schema declared.
No examples provided.
crop_image Crop image ~238
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | – |
| 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 | – | – |
No output schema declared.
No examples provided.
image_info Image info ~71
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.
| Name | Type | Req | Description |
|---|---|---|---|
| input | string | yes | Path to a JPG, PNG, WebP, AVIF, GIF, TIFF or HEIC file. |
No output schema declared.
No examples provided.
resize_image Resize image ~205
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.
| Name | Type | Req | Description |
|---|---|---|---|
| background | string | – | CSS color used to flatten transparency when the output is jpeg (default #ffffff). |
| enlarge | boolean | – | – |
| fit | string | – | – |

| height | integer | – | – |
| input | string | yes | – |
| output | string | – | Output file path. Default: next to the input, with a suffix and the right extension. |

roundcut_web_tools RoundCut web tools ~72
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.
