}

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-add-shadow",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "shadowDirection": "bottom-right",
  "shadowDistance": 15,
  "shadowBlur": 10,
  "shadowColor": "#000000",
  "shadowOpacity": 0.5,
  "shadowSize": 1,
  "backgroundColor": "transparent",
  "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.
