kotlin-sdk vs rust-sdk

Q: Which is better, kotlin-sdk or rust-sdk?

By GitHub stars, rust-sdk has more community adoption, but the best choice depends on your specific use case.

kotlin-sdk: This Kotlin SDK implements the Model Context Protocol (MCP), offering a standardized way for applications to provide context to LLMs, separating context provision from LLM interaction. It simplifies building MCP clients and servers, supporting various Kotlin platforms and standard communication transports.; rust-sdk: This is an official Rust SDK implementation for the Model Context Protocol (MCP), utilizing the Tokio async runtime. It enables developers to build and interact with AI agents by providing robust support for tools, resources, prompts, and advanced communication patterns.
