Image Convolution Kernel

Apply standard convolution kernels (blur, sharpen, edge detection, emboss) for image processing and effects

file· File resultOpen tool

Quick start

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-convolve' \
  -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-convolve' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'kernelType=blur' \
  -F 'intensity=1' \
  -F 'iterations=1' \
  -F 'outputMode=normal'

API reference

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

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/image-convolve

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Image to apply convolution kernel
kernelType	select	No	Type of convolution kernel to apply
intensity	number	No	Strength of the convolution effect (0.1-5.0)
iterations	number	No	Number of times to apply the kernel
outputMode	select

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-convolve": {
      "name": "image-convolve",
      "description": "Apply standard convolution kernels (blur, sharpen, edge detection, emboss) for image processing and effects",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-convolve",
      "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-convolve",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "kernelType": "blur",
  "intensity": 1,
  "iterations": 1,
  "outputMode": "normal"
}
  }
}

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).
