Cerbos released a query plan adapter that translates authorization policies into ChromaDB metadata filters for LangChain.js applications. The adapter enforces fine-grained access control at the vector search layer in RAG pipelines, ensuring only authorized documents are retrieved before reaching the LLM. It converts Cerbos query plans into ChromaDB Where filters, supporting logical operators, comparisons, and membership checks while handling negation through operator inversion.
