Stride Support combines retrieval-augmented generation (RAG), recommendations and tool use in a customer-support conversation. Hybrid retrieval blends BM25 word matching with BGE embeddings to find relevant products and policy passages. Recommendations combine product similarity with purchase patterns, while a fine-tuned multilingual BERT (mBERT) classifier supplies a sentiment cue for the response. A FastAPI orchestration layer gives the language model access to five Model Context Protocol (MCP) servers covering policies, products, recommendations, customers and complaints. The model can retrieve information, query an order and file or update a complaint across successive tool calls. The React interface keeps the selected purchase available throughout the conversation. Separate evaluations examine retrieval relevance, tool routing, complete responses and sentiment classification.
