Less is More: 4 design patterns for building better MCP servers

The Model Context Protocol (MCP) is gaining traction among major tech players like OpenAI, Microsoft, and Google for AI agent tool connectivity. However, it still faces significant challenges, particularly with tool hallucination and rising token costs. As more tools are introduced to an AI agent, its performance can actually decline, leading to inefficiencies in tasks that should be straightforward. This discussion is crucial as it highlights the need for better design patterns in MCP servers to enhance AI performance and manage costs effectively.
