Source: Official README and linked documentationUltraRAG can convert pipeline logic into interactive conversational Web UIs with a single click, facilitating rapid prototyping.
Source: Official README and linked documentationUltraRAG follows a modular architecture with core components like Retriever and Generation as independent MCP Servers. The MCP Client orchestrates these servers, enabling complex workflows through YAML configuration. Data flows through these components, with key technical decisions including the use of MCP for modularity and the integration of various AI services.
