MCP explained: a standardized protocol for structuring LLM context, like an API spec for prompt engineering

The author argues MCP is nascent but has immense potential once polished and standardized, explaining what problem it solves:
- Core: MCP is a standardized protocol for interacting with LLMs, defining how context (documents, chat history, embeddings, retrieval results) should be structured and passed to models during inference.
- Analogy: like an API spec for prompt engineering at scale.
- Interoperability: helps tools like LangChain, LlamaIndex, and Semantic Kernel interoperate more easily.
