What is the default embedding model?

The default embedding model is `Xenova/all-MiniLM-L6-v2`, configurable via `MCP_MEMBANK_EMBEDDING_MODEL`.

Is ChromaDB data persisted?

Yes, ChromaDB data is persisted in the named Docker volume `chromadb-data`.

What credentials does it need?

It reads `CHROMADB_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
