Crop images to specific dimensions or aspect ratios with custom positioning
Call this tool from your code in three languages.
# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/image-cropper' \
-F 'file=@/path/to/imageFile.ext'
# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-cropper' \
-F 'imageFile=/path/to/file.ext' \
-F 'cropMode=square' \
-F 'aspectRatio=16:9' \
-F 'width=0' \
-F 'height=0' \
-F 'gravity=center' \
-F 'x=0' \
-F 'y=0' \
-F 'format=original' \
-F 'quality=90'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
POST https://api.elysiatools.com/en/api/tools/image-cropper| Name | Type | Required | Description |
|---|---|---|---|
| imageFile | fileupload required | Yes | Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for cropping |
| cropMode | select | Yes | Choose how to crop your image: square, aspect ratio, exact dimensions, or custom positioning |
| aspectRatio | select | No | Select a predefined aspect ratio for cropping. The image will be cropped to match this ratio |
| width | number | No | Set the exact width for cropped area. Will be limited to image width if larger |
Add this tool to your Model Context Protocol server so AI agents can list and call it.
Add this block to your MCP client configuration:
{
"mcpServers": {
"elysiatools-image-cropper": {
"name": "image-cropper",
"description": "Crop images to specific dimensions or aspect ratios with custom positioning",

}
}
}After connecting to the SSE endpoint, list the exposed tools:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Invoke the tool by its id, passing arguments built from its parameters:
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "image-cropper",
"arguments": {
"imageFile": "https://example.com/file.ext",

"gravity": "center",
"x": 0,
"y": 0,
"format": "original",
"quality": 90
}
}
}| height |
| number |
| No |
| Set the exact height for cropped area. Will be limited to image height if larger |
| gravity | select | No | Choose where to position the crop area. Works with all crop modes |
| x | number | No | Set the horizontal position for crop area (0 = left edge). Will be adjusted if outside image bounds |
| y | number | No | Set the vertical position for crop area (0 = top edge). Will be adjusted if outside image bounds |
| format | select | No | Choose output format or keep original. Converting to JPEG may reduce quality for transparency |
| quality | number | No | Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size |
