It’s about resilience. LLMs are prone to hallucinations. Although they can be very intelligent, they don’t have 100% correct output unaided. The protocol helps increase the resilience of the output so that there’s more of a guarantee that the LLM will stay within the lines you’ve drawn around it.
That's really not true. Context is one strategy to keep a models output constrained, and tool calling allows dynamic updates to context. Mcp is a convenience layer around tool calls and the systems they integrate with
