Failure when moving a function that worked well in local STDIO to an HTTP environment is likely due to transport settings, not code issues. While StreamableHTTP is suitable for remote server connections, forcing core settings like `stateless_http` or `json_response` to true can restrict functionality. Therefore, maintaining the default value (false) is crucial.
Key takeaways
The HTTP environment has inherent limitations regarding a server's ability to proactively request information from the client.
Notification features like progress bars and log recording may be restricted by specific settings.
`stateless_http` and `json_response` must maintain their default value (false) for the function to operate properly.
The cause of failure is likely a 'setting' issue within the transport environment, rather than an error in the code itself.

Overcoming HTTP's Unidirectional Flow: The Dual SSE Connection Model
This article, based on Anthropic Academy content, explains the 'dual connection model' to overcome HTTP’s unidirectional limitations. Server-initiated requests and progress updates are sent via a persistent main SSE connection, while tool call results use a separate temporary connection.
Key takeaways
The core solution is utilizing SSE (Server-Sent Events) to bypass HTTP's single-direction limitation.
Server-driven requests use the main SSE connection, and tool results are separated onto a dedicated connection.
All communication messages must include the client identifier: mcp-session-id.
It is crucial to avoid processing progress updates and tool results on the same connection.
