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-dilate' \
  -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-dilate' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'iterations=1'

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-dilate

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	Works best with binary (black and white) images
iterations	number	No	Number of times to apply dilation. More iterations = more expansion

File-type parameters must be uploaded first via POST /upload/image-dilate, 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-dilate": {
      "name": "image-dilate",
      "description": "Apply dilation morphological operation to expand foreground objects in binary images",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-dilate",
      "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-dilate",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "iterations": 1
}
  }
}

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).
