The Model Context Protocol (MCP) is analyzed as an effort to standardize tool description and invocation for large language models (LLMs), but is argued to tackle a symptom rather than the root cause of current AI assistant limitations.
- MCP's goal is to provide a structured method for tools to define themselves and for LLMs to reliably call them, resembling advanced function calling or plugin systems.
- The central critique highlights that the primary challenge lies in the LLM's inherent reliability, its capacity for complex reasoning, consistent tool invocation, and multi-step process management.
- The article emphasizes that enhancing the fundamental "brain" of the LLM, focusing on improved agentic behavior and reasoning capabilities, is paramount.
- While MCP offers valuable standardization for tool use, it does not fundamentally resolve the core issues of LLM reliability when interacting with external APIs and managing intricate workflows.
