isStreaming property

  1. @Deprecated('Non-standard hint, honored nowhere. Enable streaming via a tool and ' 'deliver via a reactive resource (subscriptions/listen). Removed in 3.0.')
bool isStreaming
final

NON-STANDARD (makemind) legacy hint. Not part of the MCP CallToolResult spec and honored nowhere (the transport closes a tool-call stream on the final result regardless of this flag). The standard pattern is: enable streaming with a tool (tools/call) and deliver the stream via a reactive resource (subscriptions/listen on 2026-07-28, resources/ subscribe on ≤2025-11-25). Retained + still serialized for backward compatibility; slated for removal in the next major (3.0).
