I MADE MCP 94% CHEAPER (AND IT ONLY TOOK ONE COMMAND)

Summary from the TLDR Dev newsletter

AI agents using MCP incur unnecessary costs by loading entire tool catalogs as detailed JSON Schemas at the start of every session. Instead, it's better to use CLIs if available, like using the `gcloud` CLI instead of the `google_cloud` MCP. This is basically a lazy-loading approach as it allows AI to progressively understand and make CLI commands only when they are needed.
