GitHub Repository Analyzer

An LLM-powered GitHub repository analysis tool that allows users to provide a GitHub repository URL and ask natural-language questions about the repository.

The application retrieves repository information and source code through GitHub APIs exposed as MCP tools, then uses a local LLM to generate answers grounded in the retrieved repository evidence.

Features

• Analyze different GitHub repositories from the terminal

• Accept the repository URL separately from the question

• Ask questions in natural language

• Ask high-level repository questions

• Ask implementation questions about functions and code

• Search repository source code

• Read specific repository files or line ranges

• Retrieve repository metadata

• Retrieve repository file structure

• Use MCP to expose repository operations as tools

• Use LangGraph to manage the analysis workflow

• Use a local LLM through Ollama

• Ground implementation answers in retrieved repository source code

• Retry temporary GitHub API failures
