rust-mcp-sdk vs mcp-annotated-java-sdk

rust-mcp-sdk: Rust MCP SDK is a high-performance, asynchronous Rust toolkit designed for building MCP (Model Context Protocol) servers and clients. It abstracts away protocol details and transport mechanisms, allowing developers to concentrate on their core application logic. The SDK provides comprehensive support for the latest MCP protocol, including various transports and powerful procedural macros for streamlined development.; mcp-annotated-java-sdk: This SDK provides a lightweight, annotation-based framework for developing Model Context Protocol (MCP) servers in Java. It simplifies the definition and integration of MCP Resources, Prompts, and Tools, eliminating the need for Spring Framework and extensive boilerplate code.
