“Implementation detail” is doing a lot of work in the second sentence, though. There are whole startups like langchain that were trying to build out a reasonable agent framework integrated in such a way that the LLMs can drive. MCP makes that really easy — LLM training just has to happen once, against MCP spec, and I get client and LLM support for an iterative tool use scenario right in the LLM.
