DocNav

DocNav is an MCP server that enables LLMs to intelligently read, navigate, and analyze long-form documents by breaking them into hierarchical tree structures similar to DOM nodes. The implementation supports Markdown and PDF files through pluggable processors, converting documents into navigable sections with auto-generated UUIDs for security, and provides tools for outline generation, section-by-section reading, content search, and contextual navigation with parent-child-sibling relationships. Built with a modular architecture using Python, it's particularly valuable for document analysis workflows where LLMs need to understand document structure and navigate large texts systematically rather than processing them as monolithic blocks.
