Worked on the modelcontextprotocol/kotlin-sdk repository to deliver a ClientConnection context receiver for server call handlers, enabling tools to access the client channel directly from server handlers for notifications, logging, and elicitation. This feature required careful API design in Kotlin, focusing on server development and integration testing to ensure reliable end-to-end behavior. The update introduced a breaking change for existing tool handlers, but established a foundation for a more interface-driven, future-compatible Context design. Integration tests were implemented to validate the new functionality, and documentation was updated to guide users through the transition and highlight the strategic direction of the API.
