MCP can be used as a form of context augmentation (i.e., RAG). It allows models to specify how that context augmentation is generated through tool use. It's a formalized way of allowing developers to implement tools (using JSON-RPC) in such a way that the model is provided with a menu of tools that it can call on in each generation. The output is then included in the next generation.
