I made, and use this: https://github.com/libragen/libragen

It’s a CLI tool and MCP server for creating discrete, versioned “libraries” of RAG-able content.

Under the hood, it uses an embedding model locally. It chunks your content and stores embeddings in SQLite. The search functionality uses vector + keyword search + a re-ranking model.

You can also point it at any GitHub repo and it will create a RAG DB out of it.

You can also use the MCP server to create and query the libraries.

Your README references a file named LICENSE which doesn't seem to exist on the main branch.
