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-gamma-correction' \
  -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-gamma-correction' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'gamma=1' \
  -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-gamma-correction

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for gamma correction
gamma	range	No	Gamma correction (0.1 = darker, 1.0 = original, 3.0 = brighter)
format	select	No	Choose output format or keep original. PNG recommended for maximum quality
quality	number	No	Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

File-type parameters must be uploaded first via POST /upload/image-gamma-correction, then the returned filePath is passed to the corresponding file field.

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-gamma-correction": {
      "name": "image-gamma-correction",
      "description": "Apply gamma correction to adjust image brightness non-linearly for better visual perception",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-gamma-correction",
      "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-gamma-correction",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "gamma": 1,
  "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).
