AST2LLM for Go is a powerful local MCP server designed to significantly improve the accuracy and efficiency of Large Language Models (LLMs) when interacting with Go code. By precisely analyzing Go project structures and identifying key elements like external type declarations using AST analysis, it automatically injects relevant code context directly into LLM prompts. This approach provides 3-5x faster context resolution compared to traditional graph-based methods, enabling LLMs to better understand and generate Go-related content, such as resolving missing information about struct fields.
