Build an MCP Server in Go (for Claude Code)

Short summary

A practical guide to building MCP (Model Context Protocol) servers in Go using the official SDK, covering tool declaration, transport selection, and production concerns. The key architectural decision is stdio vs HTTP: stdio for personal local tools, HTTP for shared team services requiring auth. The SDK infers JSON schemas from Go structs, and tool descriptions serve as the model's interface — no prompts needed.

• •MCP servers expose typed tools that Claude Code discovers and calls autonomously
• •Choose stdio for local personal tools, HTTP for shared team services with auth
• •SDK infers JSON schema from Go structs; tool descriptions are your interface to the model
