Model Context Protocol
解决什么问题What problem it solves
一套标准接口，让 AI 用统一的方式接外部工具和数据。不用为每个服务单独适配。A standard interface for connecting AI to external tools and data in one uniform way, without a bespoke integration per service.
这是什么What it is
Anthropic 提出的开放协议。它用统一规范描述「AI 可以调哪些工具、可以读哪些资源」。
它的作用类似 AI 世界的 USB-C：接什么设备都能用同一套接口。
An open protocol proposed by Anthropic describing, in one specification, which tools an AI may call and which resources it may read.
It plays the role of USB-C for AI: whatever device you plug in, the interface is the same.
