An official SDK for developers who want to build MCP servers in Go. It abstracts MCP core primitives (tools, resources, and prompts) in a type-safe way. This SDK runs in Go 1.21 or later environments and supports both stdio and Streamable HTTP transports. You can naturally add MCP capabilities to an existing Go codebase. ## What problems does it solve? - ('In Go projects', 'when you need to implement an MCP server or client', 'ensure protocol compliance with official primitives') - ('Type safety', 'when you need to prevent incorrect protocol usage at compile time', 'catch mistakes early with the type system') - ('Multiple transports', 'when you need to support both local stdio and remote HTTP', 'choose the transport that fits your deployment environment') ## Key Features ### Server implementation Server API for registering tools, resources, and prompts - **Use case**: Expose external tools through MCP - **Outcome**: Type-safe server definition - **Limitations**: Requires protocol learning ### Client implementation Client API for connecting to MCP servers - **Use case**: Call servers from an agent - **Outcome**: Connect using the standard protocol - **Limitations**: Requires authentication setup ### Transport layer Built-in stdio and Streamable HTTP transports - **Use case**: Support both local and remote - **Outcome**: Deploy without changing transports - **Limitations**: Requires CORS and authentication for remote ## Installation and Execution ### go Install using the Go package manager. ``` go get github.com/modelcontextprotocol/go-sdk ``` ## Real-world Usage Examples ### Starting the server go run ./cmd/server ``` Run the MCP server over stdio. ``` ## Advantages and Limitations ### Advantages - Official MCP project, ensuring protocol compliance - Go idiomatic development patterns - Multiple transport support ### Points to Consider Before Use - Requires the Go runtime to be installed - Timing of support for the 2026 specification varies by SDK ## Comparison with Similar Programs | Program | Characteristics | Best Suited For | | --- | --- | --- | | SDKs in other languages | Implement the same MCP in other languages | Multi-language teams | | Direct implementation | Parse the protocol directly | Minimal dependencies | ## Official Resources and Further Learning - [Official homepage](https://modelcontextprotocol.io/docs/sdk) — https://modelcontextprotocol.io/docs/sdk - [Official documentation / knowledge base](https://github.com/modelcontextprotocol/go-sdk-sdk) — https://github.com/modelcontextprotocol/go-sdk-sdk - [Installation / distribution](go get github.com/modelcontextprotocol/go-sdk) — go get github.com/modelcontextprotocol/go-sdk - [Release notes](https://github.com/modelcontextprotocol/go-sdk-sdk/releases) — https://github.com/modelcontextprotocol/go-sdk-sdk/releases - [Source / development resources](https://github.com/modelcontextprotocol/go-sdk-sdk) — https://github.com/modelcontextprotocol/go-sdk-sdk Version and supported environment information is from the official site as of 2026-10-18.
