Repo GraphRAG

About

Repo GraphRAG is an MCP (Model Context Protocol) server designed to transform your codebase and documentation into an interactive knowledge graph. By leveraging LightRAG and Tree-sitter, it intelligently analyzes code and text documents within a repository to construct a comprehensive knowledge base. This powerful tool then facilitates intelligent Q&A, provides detailed implementation plans, and suggests concrete change steps, making it invaluable for understanding, modifying, and evolving complex software projects.

Key Features

• Builds and incrementally updates a repository knowledge graph from code and text documents.
• Generates detailed implementation plans and concrete change steps for modification requests.
• Answers questions about the codebase based on the knowledge graph, optionally combined with vector search.
• Supports knowledge graph extraction for 12 programming languages including Python, C++, Java, and JavaScript.
• Features intelligent entity merging based on semantic similarity to consolidate code and documentation references.
• 0 GitHub stars

Use Cases

• Facilitating code comprehension and onboarding for new developers by providing a navigable knowledge graph.
• Generating structured implementation plans for new features or modifications within a project.
• Understanding complex codebases and documentation through interactive Q&A.
