How to Install CodeGraph RAG on Ubuntu 24.04

CodeGraph RAG is a local-first code intelligence platform that indexes your entire monorepo into a hybrid knowledge graph combining Memgraph (graph database) and Qdrant (vector database). It lets developers query codebases in natural language, explore cross-language dependencies, understand architecture, and even perform AI-assisted edits across dozens of languages using tree-sitter parsing. It ships as both a CLI and an MCP (Model Context Protocol) server, so it plugs directly into Cursor, Claude Code, and other AI assistants. Self-hosted, MIT-licensed, and designed for monorepos of any size.
