godoc-mcp

Overview

godoc-mcp is a specialized MCP server designed to improve LLM performance when working with Go code by replacing full source file dumps with structured documentation. It significantly reduces context usage while maintaining access to essential package information, including exported symbols, documentation, and source code. The server supports multiple transport modes (stdio, SSE, HTTP) and works with both local Go projects and external package documentation through Go's module system.
