UltraRAG
ActiveDescription
A low-code MCP framework for building complex and innovative RAG pipelines. Combines visual pipeline design with MCP protocol integration for end-to-end RAG — from data ingestion and chunking to retrieval and generation.
Key Features
- First lightweight RAG framework built on MCP architecture
- Low-code YAML configuration for complex RAG workflow orchestration
- Core components (retriever, generator, etc.) as independent MCP Servers
- Built-in unified evaluation system with mainstream research benchmarks
- Visual Pipeline Builder with bidirectional sync between Canvas and code
Use Cases
💡 Rapid end-to-end RAG system setup: ingestion, chunking, retrieval to generation
💡 RAG research experiments: standardized evaluation workflows and benchmark comparison
💡 Interactive RAG prototyping: pipeline logic converts to conversational Web UI in one click
💡 Knowledge base Q&A: build custom knowledge bases for document Q&A
Strengths & Limitations
