In February 2026, JNett96 developed a ClientConnection context receiver for server call handlers in the modelcontextprotocol/kotlin-sdk repository. This feature allowed tools to access the client channel directly from server handlers, supporting notifications, logging, and elicitation to enhance runtime observability and tooling integration. The implementation, written in Kotlin and focused on API design and server development, introduced a breaking change for existing tool handlers but established a more future-proof, interface-based Context architecture. JNett96 validated the new functionality with integration testing, ensuring reliable end-to-end behavior and documenting the migration path to maintain clarity for future development efforts.
