Developer creates Mindex to fix RAG's blind spot by adding knowledge graphs to preserve document relationships

3 Key Points

  1. Traditional RAG systems retrieve relevant text chunks but lose critical relationships between documents, a major limitation for complex systems like APIs and infrastructure

  2. Mindex combines semantic search with a knowledge graph layer to surface how documents and information relate to each other rather than returning isolated chunks

  3. The tool integrates via CLI and MCP protocol, enabling direct integration with Claude Code, Cursor, and custom AI agents for developers and tooling builders
