Best When

You want a production-quality, local-first RAG system with strong document structure awareness, citations, and MCP integration for AI assistant workflows.

Avoid When

You need a managed RAG-as-a-service solution or your documents are primarily unstructured web content rather than PDFs and structured documents.

Use Cases

  • Indexing and querying a personal or enterprise document library with citation-backed answers (page numbers, section headings)
  • Running multi-agent research workflows that plan, search, evaluate, and synthesize across a document corpus
  • Integrating a local document knowledge base into Claude Desktop or other MCP clients via the built-in MCP server

Not For

  • Cloud-first teams that need managed vector database infrastructure without self-hosting
  • Simple keyword search use cases where a full RAG pipeline adds unnecessary complexity
  • Non-Python shops or teams without Python 3.12+ capability
