Overview

Rag-rat is a local repository intelligence tool that indexes codebases for semantic search, symbol navigation, and impact analysis. It operates as an MCP (Model Context Protocol) server and integrates with git and GitHub to provide a change history trail. The tool builds a source-anchored memory graph to support contextual code understanding.
