• Automatic Embedding: Content is automatically embedded using OpenRouter's text-embedding-3-large model
• Semantic Search: 4 MCP tools provide semantic search capabilities for LLM applications
• Real-time Management: Web interface for enabling/disabling and monitoring embeddings
• Error Tracking: Comprehensive error logging and debugging capabilities

MCP Tools Available

• search_shipping_info(shop_id, query, limit?) - Search shipping and delivery information
• search_contact_info(shop_id, query, limit?) - Search contact and support information
• search_terms_info(shop_id, query, limit?) - Search terms of service and policies
• search_faq_info(shop_id, query, limit?) - Search frequently asked questions

See the Qdrant Setup Guide for complete configuration instructions.
