Simon Willison 回应“MCP 从来不是好主意”：它仍有用武之地
Comment: MCP was always a bad idea?
Simon Willison 在 Hacker News 评论中反驳“MCP 从来不是好主意”的观点，认为该文完全忽视了 MCP 当下的价值。他指出，若运行 Claude Code、Codex、Meta Muse、OpenClaw 等拥有不受限互联网访问的完整终端智能体，确实几乎无需 MCP，可直接调用 API；但若想构建不那么“YOLO”的系统，MCP 能让这些需求更容易实现。

Comment My comment on MCP was always a bad idea? — Hacker News
This article entirely misses the value that MCP brings today.
Sure, there's almost no reason to use MCPs if you are running a full-blown terminal agent (Claude Code, Codex, Meta Muse, OpenClaw etc) with unfettered internet access - just let it call APIs directly.
If you want to operate something that's less YOLO than that, you'll find yourself wanting:
MCP makes all of that so much easier to provide.
Thinking MCP is obsolete because full coding agents don't need it misses out on all of the other things we might want to build.
