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": "social-media-template-resize-grid",
    "arguments": {
  "image": "https://example.com/file.ext",
  "includeInstagram": true,
  "includeX": true,
  "includeLinkedIn": true,
  "includeYouTube": true,

  "fitMode": "cover",
  "backgroundColor": "#111827",
  "showSafeZones": true,
  "outputFormat": "jpeg",
  "quality": 88
}
  }
}

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.
