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-clahe' \
  -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-clahe' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'tileSize=64' \
  -F 'contrastLimit=3' \
  -F 'brightnessLimit=0.01' \
  -F 'gridSize=8' \
  -F 'format=original' \
  -F 'quality=95'

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-clahe

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to apply CLAHE histogram equalization
tileSize	range	No	Size of tiles for local histogram equalization. Smaller tiles provide more local contrast enhancement
contrastLimit	range	No	Contrast amplification limit. Higher values allow stronger contrast enhancement but may amplify noise
brightnessLimit	range	No	Brightness amplification limit. Lower values prevent over-amplification of bright areas

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-clahe": {
      "name": "image-clahe",
      "description": "Apply Contrast Limited Adaptive Histogram Equalization for local contrast enhancement",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-clahe",
      "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-clahe",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "tileSize": 64,
  "contrastLimit": 3,
  "brightnessLimit": 0.01,
  "gridSize": 8,
  "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).
