What MCP Go SDK does

A library that provides Go APIs for constructing and using MCP clients and servers.

Why teams reach for it: It is the official Model Context Protocol SDK for Go, published in the modelcontextprotocol organisation and aiming to implement the full MCP spec, where the established Go alternatives (mcp-go, mcp-golang, go-mcp) are third-party projects.

What will you use to implement the protocol?

A framework or SDK gives developers pre-built code for creating an MCP server or client, so they don't have to implement the protocol from scratch.
