rust-mcp-sdk vs sdk-go
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.; sdk-go: The Temporal Go SDK is a framework designed for authoring workflows and activities in the Go programming language. It enables developers to build scalable, durable, and highly available distributed applications leveraging the Temporal orchestration engine.
01
TL;DR
Choose rust-mcp-sdk if…Building high-performance MCP servers that interact with various clients using different transport mechanisms (Stdio, HTTP).
Choose sdk-go if…Building long-running business logic in distributed applications.
