Call this tool from your code in three languages.

cURL

# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/image-scaling' \
  -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-scaling' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'scaleX=1.0' \
  -F 'scaleY=1.0' \
  -F 'uniform=true' \
  -F 'background=transparent' \
  -F 'format=original' \
  -F 'quality=95'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-image-scaling": {
      "name": "image-scaling",
      "description": "Apply scaling transformation to images with visual matrix representation. Supports uniform and non-uniform scaling with real-time preview.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-scaling",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "image-scaling",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "scaleX": "1.0",
  "scaleY": "1.0",
  "uniform": true,
  "background": "transparent",
  "format": "original",
  "quality": 95
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
