MCP tools · 7 exposed · ~1,108 tokens

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 →

Tool Tokens
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.

NameTypeReqDescription
backgroundstring–CSS color used to flatten transparency when the output is jpeg (default #ffffff).
formatstring––
inputstringyes–
outputstring–Output file path. Default: next to the input, with a suffix and the right extension.
previewboolean–Attach a small JPEG preview to the result (default true).
qualityinteger–Lossy quality 1-100 (default 80). Ignored for png.
sizeinteger–Output side in pixels (default: the largest centered square).

No output schema declared.

No examples provided.

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.

NameTypeReqDescription
inputstringyes–
outputstring–Output file path. Default: next to the input, with a suffix and the right extension.
previewboolean–Attach a small JPEG preview to the result (default true).
qualityinteger–Lossy quality 1-100 (default 80). Ignored for png.

No output schema declared.

No examples provided.

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.

NameTypeReqDescription
backgroundstring–CSS color used to flatten transparency when the output is jpeg (default #ffffff).
formatstringyes–
inputstringyes–
outputstring–Output file path. Default: next to the input, with a suffix and the right extension.
previewboolean–Attach a small JPEG preview to the result (default true).
qualityinteger–Lossy quality 1-100 (default 80). Ignored for png.

No output schema declared.

No examples provided.

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.

NameTypeReqDescription
aspectstring–Centered crop to this ratio, e.g. 16:9. Overrides the pixel box.
backgroundstring–CSS color used to flatten transparency when the output is jpeg (default #ffffff).

topinteger––
widthinteger––

No output schema declared.

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.

NameTypeReqDescription
inputstringyesPath to a JPG, PNG, WebP, AVIF, GIF, TIFF or HEIC file.

No output schema declared.

No examples provided.

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.

NameTypeReqDescription
backgroundstring–CSS color used to flatten transparency when the output is jpeg (default #ffffff).

No output schema declared.

No examples provided.

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.
