Recent fixes
Introduce Configuration class for StreamableHttpServerTransport Replace the six-parameter flat constructor of with a typed class. This improves API ergonomics, enables structural equality and copy(), and provides a stable extension point for future options without further breaking the constructor signature. Changes: Add as a public class nested directly on , with as the first parameter (most commonly set) Change the primary constructor to accept . Rename to in Configuration, aligning with Kotlin's type-safe time API Deprecate the old flat constructor with a compatibility bridge Update KotlinTestBase integration test to use the new constructor Enable test AbstractResourceIntegrationTest.testSubscribeAndUnsubscribe() since #249 is closed Motivation and Context The current StreamableHttpServerTransport API cannot be easily extended: adding more parameters would be a breaking change. But this is already needed for #521. This PR is a prerequisite for #535 How Has This Been Tested? Regression tests Breaking Changes No. Current StreamableHttpServerTransport constructor was deprecated Types of changes [ ] Bug fix (non-breaking change which fixes an issue) [x] New feature (non-breaking change which adds functionality) [ ] Breaking change (fix or feature that would cause existing functionality to change) [ ] Documentation update Checklist [x] I have read the MCP Documentation [x] My code follows the repository's style guidelines [x] New and existing tests pass locally [ ] I have added appropriate error handling [ ] I have added or updated documentation as needed
