The Model Context Protocol (MCP) has established itself as the ubiquitous standard for connecting AI applications to external systems. Since its release, there have been implementations across various programming languages and frameworks, enabling developers to build solutions that expose data sources, tools, and workflows to AI applications.

For Go developers, however, the journey to an official MCP SDK took longer (compared to other SDKs like Python and TypeScript). Discussions and design/implementation work on the official Go implementation began during early to mid 2025. At the time of writing (January 2026), it stands at version 1.2.0. As a Gopher, I’m excited (and relieved!) to finally have a stable, official MCP Go SDK that the Go community can rely on.
