hamr

概述

hamr是一个极简的Go语言MCP服务器框架，通过从Go结构体标签自动生成JSON模式来消除样板代码。它比官方Go SDK提供了更高级的抽象，包含工具分组、最小模式、响应截断、成本跟踪和中间件支持等功能。该框架特别专注于减少AI对话中的令牌开销，使其对效率至关重要的生产环境使用特别理想。

FAQ

hamr与官方Go SDK有什么区别？

hamr是在官方SDK基础上构建的高级框架，专注于人体工程学和令牌优化。它提供自动模式生成、工具分组、中间件和内置优化功能（如最小模式和响应截断），而SDK不提供这些功能。

如果我需要最新的MCP协议功能，可以使用hamr吗？

官方Go SDK将始终最先获得新的协议功能。hamr最适合令牌优化和开发生产力是优先级的用例，而不是用于前沿协议支持。
