MCP + RAG: Why I Stopped Building Complex RAG Systems After MCP Changed Everything

MCP + RAG: Why I Stopped Building Complex RAG Systems After MCP Changed Everything

Honestly, I've spent the last four years building increasingly complex RAG systems. Chunking strategies, embedding models, vector databases, rerankers, hybrid search... you name it, I've probably wasted a weekend trying it.

I had this 1,800-hour knowledge base project called Papers — six years of notes, articles, bookmarks, everything. I built RAG version after RAG version, each time thinking "this time it'll be perfect."

Spoiler: It never was.

Then I added MCP (Model Context Protocol) support. And I realized something that completely changed how I think about knowledge retrieval: MCP makes traditional complex RAG obsolete for most use cases.
