Build and Run a Go MCP Server in 5Mins

2025–04–10 Update

The Go team at Google is working with Anthropic to build and support an official Go MCP SDK! Proposal: official support for modelcontextprotocol/go-sdk https://github.com/orgs/modelcontextprotocol/discussions/224

In this tutorial, I will go through the end to end flow to build a MCP Go Server in 5Mins. This Go MCP Server will leverage MCP Go Library from mark3labs.

Benefit of Using Go for MCP Server

Using Go (Golang) to build a Model Context Protocol (MCP) server makes a lot of sense for several practical and architectural reasons. Here’s a breakdown of why Go is a strong choice for building a protocol server like MCP:

Performance with Concurrency

• Go was designed for building high-performance network services.
• Its goroutines (lightweight threads) and channel-based concurrency make it easy to handle many simultaneous connections with low overhead.
• This is perfect for a protocol server that needs to serve multiple model context requests in parallel.

Ease of Building and Deployment

• Go compiles into a single static binary, making deployment and distribution extremely easy — especially for microservices or edge deployments.
• Great for containerized environments like Kubernetes.
