Example call

The client initializes the MCP connection before sending this JSON-RPC call. Example records are fictional.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_attachments",
    "arguments": {
      "taskId": "22222222-2222-4222-8222-222222222222",
      "limit": 50
    }
  }
}

Example result

Mill returns this object in structuredContent and normally a JSON text content block (large responses may shorten the text block). A tool failure sets isError; never treat an error as a completed mutation.

{
  "items": [
    {
      "id": "44444444-4444-4444-8444-444444444444",
      "taskId": "22222222-2222-4222-8222-222222222222",
      "fileName": "restore-report.pdf",
      "contentType": "application/pdf",
      "sizeBytes": 2048,
      "createdBy": "66666666-6666-4666-8666-666666666666",
      "createdAt": "2027-01-18T09:30:00.000Z"
