# Sean Lynch：MCP的核心价值在于将认证流隔离在上下文窗口之外

开发者 Sean Lynch 指出，MCP（Model Context Protocol）相比传统的 Skills 或 CLI，真正的优势在于能够将认证流程隔离在 Agent 的上下文窗口之外，甚至完全独立于框架之外。他认为 MCP 的理想形态可能仅仅是一个 API 认证网关，即便仅实现这一点也是一大胜利。

## English Version

**Sean Lynch: MCP's Core Value Is Isolating Auth Flow Outside Context Window**

Developer Sean Lynch argues that MCP's real advantage over Skills or CLI is isolating the authentication flow outside the agent's context window. He suggests the idealized form of MCP might simply be an auth gateway for the API.
