Large language models<\/a> are a treasure trove of data, but until last year, their use was limited to basic Q\/A based on their training data. Then came the concept of RAG, a breakthrough that helped us connect our data sources with LLMs to create personalized, credible systems. Now with MCP, we are taking the way we work with LLMs a step ahead by connecting them with external tools. So, is RAG vs MCP a thing, or are these complementary technologies that can enhance the outputs we get from LLMs? In this article, we will break down the differences between the MCP and RAG and understand how we can use the two together to build sophisticated solutions with LLMs.<\/p>\n

What is RAG?<\/h2>\n

RAG<\/a> or Retrieval Augmented Generation combines the power of information retrieval into the generation process. Usually, LLMs solely rely on their training data to generate the responses for user queries, which would sometimes lead to incorrect or biased results. With RAG, LLMs can retrieve external information during the output generation process, bridging the gap between LLM\u2019s static training knowledge and dynamic information.<\/p>\n

Here is how a RAG system works:<\/p>\n
