This article discusses the challenge of integrating Large Language Models (LLMs) with external tools, likening the LLM's inability to act on its knowledge to a disembodied brain. The author introduces the Model Context Protocol (MCP) and LangGraph as solutions to enable LLMs to make tool calls independently, effectively giving them "hands" to interact with the world. A code example demonstrates how to use these technologies to create an LLM capable of making tool calls from scratch, while also warning about the potential for infinite loops if the state graph is not carefully designed. AI
IMPACT Enables LLMs to interact with external services, moving towards more autonomous AI agents.
RANK_REASON Article describes a technical approach to enabling LLM tool calls using existing frameworks, not a new model release or significant industry event.
