Worked on the modelcontextprotocol/rust-sdk repository to decouple the HTTP server framework from a specific dependency, focusing on reducing the build footprint and improving flexibility for downstream users. Used Rust for backend development and dependency management, removing the unused axum dependency from the server-side-http feature and relocating it to dev-dependencies for testing purposes. This approach minimized transitive dependencies and potential conflicts, allowing users to select their preferred HTTP server or framework without altering existing examples. Updated the testing strategy to ensure integration coverage while keeping axum out of the main library dependencies, resulting in a more modular and maintainable codebase.
