Community Go SDK for MCP servers and clients.

Visit projectmark3labs/mcp-go

A pre-official Go SDK for MCP, widely used in production. Define servers and clients with a fluent Go API; supports stdio and HTTP transports.

What it does

  • Community Go implementation of MCP (mark3labs/mcp-go) — build MCP servers and clients in Go
  • Aims at full spec coverage: tools, resources, prompts over stdio/SSE/HTTP transports
  • Widely used de-facto Go SDK alongside the official modelcontextprotocol/go-sdk

When to use it

Write a Go MCP server with batteries included — high-level server API, transport handled, when the official SDK's minimalism isn't what you want.

Getting started

go get github.com/mark3labs/mcp-go

Check go.mod for the current minimum Go version.

Things to know

README itself flags 'under active development' — advanced spec features may lag. Two Go SDKs exist (this + official); pick per API style and maintenance pace.
