This post explains the why and the how.https://site.fredlab.dev/blog/mcp-vs-rest-for-rag-in-fred-why-we-run-both/Sun, 17 Aug 2025 10:00:00 +0200https://site.fredlab.dev/blog/mcp-vs-rest-for-rag-in-fred-why-we-run-both/Fred uses REST for graph-driven RAG (Rico, Rico Pro) and MCP for tool-driven RAG (Dominic). Running both lets us measure latency, reliability, governance, and developer ergonomics—without changing our UI or schemas.https://site.fredlab.dev/blog/rico-learns-to-reflect-smarter-document-qa-with-self-rag-techniques/Tue, 05 Aug 2025 17:00:00 +0200https://site.fredlab.dev/blog/rico-learns-to-reflect-smarter-document-qa-with-self-rag-techniques/Rico, the document expert agent in Fred, now leverages Self-RAG-inspired strategies to assess document quality, retry with smarter queries, and generate more accurate answers. This post explains the improvements.
