Updated ModelContextProtocol from 1.4.0 to 1.4.1.

Release notes

Sourced from ModelContextProtocol's releases.

1.4.1

This release backports a memory-leak fix for HTTP/SSE-based MCP servers. StreamableHttpServerTransport now releases its Server-Sent Events response stream reference as soon as a GET request ends, instead of holding it until the session is disposed via explicit DELETE or idle timeout. Long-lived SSE clients that disconnect without sending DELETE no longer pin the underlying Kestrel connection and its associated memory-pool buffers (~20 MiB per session), preventing the sustained memory growth that could accumulate under connect/disconnect churn.

What's Changed

  • Release SSE response stream reference when GET request ends #​1628 by @​halter73 (co-authored by @​joelmforsyth @​Copilot)

Acknowledgements

  • @​slomangino123 submitted issue #​766 (resolved by #​1628)
