  -F 'file=@/path/to/tileImages.ext'

# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-mosaic-generator' \
  -F 'mainImage=/path/to/file.ext' \
  -F 'tileImages=/path/to/file.ext' \

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-mosaic-generator": {
      "name": "image-mosaic-generator",
      "description": "Create stunning photo mosaics by combining hundreds of small images to form a larger main image. Each tile is carefully selected to match the colors of the underlying image.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-mosaic-generator",
      "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-mosaic-generator",
    "arguments": {
  "mainImage": "https://example.com/file.ext",
  "tileImages": "https://example.com/file.ext",
  "tileSize": 50,
  "tileResolution": 30,
  "overlapTiles": false,
  "blendingMode": "normal",
  "outputFormat": "png",
  "quality": 90
}
  }
}

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).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
