Core Features

Low-Code Orchestration

UltraRAG allows developers to orchestrate complex workflows with YAML configuration, reducing the need for extensive coding.

Source: per README
Modular Extension

Based on the MCP architecture, UltraRAG decouples functions into independent Servers, enabling seamless integration of new features and high reusability.

Source: per README
Unified Evaluation

The framework includes built-in evaluation workflows and benchmarks, enhancing reproducibility and comparison efficiency in research.

Source: per README
Rapid Prototype Generation

UltraRAG can convert pipeline logic into interactive conversational Web UIs with a single click, facilitating rapid prototyping.

Source: per README

Architecture

UltraRAG 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.
