Rag Overview
The rag MCP server indexes local document collections and exposes hybrid keyword and semantic search across multiple knowledge bases. It stores chunks, embeddings, metadata, and queue state in SQLite, while optional AI contextualization adds bilingual Korean and English retrieval terms. Use it when an agent needs to search DOCX, HWPX, PDF, spreadsheet, presentation, or audio content stored on a local filesystem. Standard MCP stdio transport supports interactive search while indexing can continue through separate command-line workflows.
- Search local Korean and English document collections
- Index scanned PDFs with OCR fallback
- Retrieve full text for matching document chunks
- Queue incremental reindexing after filesystem changes
