1. Repository làm gì?
Code-Graph-RAG parses a multi-language codebase with Tree-sitter, sharpened by compiler-grade frontends and runtime traces where available, builds a knowledge graph of its structure in Memgraph, and lets you query, edit, and optimise that code in plain English. It works across a monorepo of mixed languages under one unified graph schema.
See NEWS.md for the full history.
Point Code-Graph-RAG at a repository and it reads every source file, extracts functions, classes, methods, modules, and the relationships between them, and stores the result as an interconnected graph. Once the graph exists you can:
See the Architecture Overview and Graph Schema for the full picture.
Python, TypeScript, TSX, JavaScript, Rust, Go, Java, C, C++, C#, PHP, Lua, and Dart are fully supported. Scala is in development, and Ruby, Kotlin, Swift, Elixir, Haskell, Solidity, Bash, and Nix have structural support (modules, functions, classes where the language has them, and imports) through the pluggable ast-grep tier. See the Language Support matrix for per-language capabilities.
cgr is published to PyPI. Install it system-wide with the treesitter-full (all languages) and semantic (vector search) extras:
2. Dữ liệu và cấu trúc đáng chú ý
Three version lines exist and they intentionally differ:
So the newest tag on main usually runs ahead of the newest release, often by tens of patch versions; they coincide only just after a release. Nothing is stuck, the cadences differ by design. A security fix does NOT wait for the cadence: it ships a release and a PyPI upload immediately.
uv tool install and pipx install give you the newest PyPI version, which is the newest RELEASE, not the newest tag. Interim tags exist so every merge is addressable; binaries and PyPI uploads follow the cadence above.
To run code newer than the latest release, install from git:
To upgrade an existing install, run uv tool upgrade code-graph-rag (with pipx, pipx upgrade code-graph-rag, or pipx reinstall code-graph-rag for a git install). Upgrade covers the other install methods.
You also need Python 3.12+, Docker (for Memgraph), cmake, and ripgrep. Full prerequisites, source installs, and environment setup are in the Installation guide.
The wheel is pure Python (py3-none-any), so it installs on any platform with Python 3.12 or newer. Older system interpreters (Debian Bookworm ships 3.11) need the interpreter pinned explicitly; see Installation for the commands.
3. Khả năng ứng dụng và giới hạn
Repeat the first command for each repository you want indexed; the graph is shared, and syncing one project leaves the others alone. To start over from an empty graph, add –clean — it deletes every project in the shared graph, not just this one, and asks for confirmation first when other projects would be destroyed.
The Quick Start guide walks through parsing, querying, and exporting in five minutes.
Code-Graph-RAG runs as an MCP server so Claude Code and other MCP clients can query and edit your codebase directly. See the MCP Server guide for setup.
Code-Graph-RAG is open source and free to use. For organisations that need more, we offer fully managed cloud-hosted solutions and on-premise deployments:
We also offer custom development, integration consulting, technical support contracts, and team training.
