My own interest in MCPs has waned ever since I started taking coding agents seriously. Almost everything I might achieve with an MCP can be handled by a CLI tool instead. LLMs know how to call cli-tool –help, which means you don’t have to spend many tokens describing how to use them—the model can figure it out later when it needs to.
