# MCP Go SDK [](https://codespaces.new/modelcontextprotocol/go-sdk) [](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk) [](https://scorecard.dev/viewer/?uri=github.com/modelcontextprotocol/go-sdk) This repository contains an implementation of the official Go software development kit (SDK) for the Model Context Protocol (MCP). ## Package / Feature documentation The SDK consists of several importable packages: - The [`github.com/modelcontextprotocol/go-sdk/mcp`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp) package defines the primary APIs for constructing and using MCP clients and servers. - The [`github.com/modelcontextprotocol/go-sdk/jsonrpc`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/jsonrpc) package is for users implementing their own transports. - The [`github.com/modelcontextprotocol/go-sdk/auth`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/auth) package provides some primitives for supporting OAuth. - The [`github.com/modelcontextprotocol/go-sdk/oauthex`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/oauthex) package provides extensions to the OAuth protocol, such as ProtectedResourceMetadata. The SDK endeavors to implement the full MCP spec. The [`docs/`](/docs/) directory contains feature documentation, mapping the MCP spec to the packages above. ## Version Compatibility The following table shows which versions of the Go SDK support which versions of the MCP specification: | SDK Version | Latest MCP Spec | All Supported MCP Specs | |-----------------|-------------------|----------------------------------------------------| | v1.4.0+ | 2025-11-25\* | 2025-11-25\*, 2025-06-18, 2025-03-26, 2024-11-05 | | v1.2.0 - v1.3.1 | 2025-11-25\*\* | 2025-11-25\*\*, 2025-06-18, 2025-03-26, 2024-11-05 | | v1.0.0 - v1.1.0 | 2025-06-18 | 2025-06-18, 2025-03-26, 2024-11-05 | \* Client side OAuth has experimental support. \*\* Partial support for 2025-11-25 (client side OAuth and Sampling with tools not available). New releases of the SDK target only supported versions of Go. See https://go.dev/doc/devel/release#policy for more information. ## Getting started To get started creating an MCP server, create an `mcp.Server` instance, add features to it, and then run it over an `mcp.Transport`. For example, this server adds a single simple tool, and then connects it to clients over stdin/stdout: ```go package main import ( "context" "log" "github.com/modelcontextprotocol/go-sdk/mcp" ) type Input struct { Name string `json:"name" jsonschema:"the name of the person to greet"` } type Output struct { Greeting string `json:"greeting" jsonschema:"the greeting to tell to the user"` } func SayHi(ctx context.Context, req *mcp.CallToolRequest, input Input) ( *mcp.CallToolResult, Output, error, ) { return nil, Output{Greeting: "Hi " + input.Name}, nil } func main() { // Create a server with a single tool. server := mcp.NewServer(&mcp.Implementation{Name: "greeter", Version: "v1.0.0"}, nil) mcp.AddTool(server, &mcp.Tool{Name: "greet", Description: "say hi"}, SayHi) // Run the server over stdin/stdout, until the client disconnects....
