A Model Context Protocol (MCP) server that provides real-time access to Go package documentation from pkg.go.dev, ensuring LLMs always have the latest and most accurate Go ecosystem information.
The godoc-mcp server is designed to bridge the gap between rapidly evolving Go package documentation and the static knowledge of Large Language Models (LLMs). By integrating with pkg.go.dev, it offers real-time access to the latest Go package documentation, ensuring that developers and LLMs have the most current information at their fingertips. This server supports comprehensive coverage of public Go packages, allowing users to search for packages by name or functionality, and even query specific versions. With intelligent caching mechanisms, godoc-mcp provides fast and reliable responses, even in the face of network issues. Its seamless integration with any MCP-compatible LLM client makes it a versatile tool for developers looking to stay updated with the Go ecosystem.
