Cons

-需要 Node.js 22.7.5+ 环境，对运行环境有特定要求
-主要面向 MCP 服务器开发者，普通用户使用场景有限
-作为调试工具，不适合生产环境部署使用

-Version 2 is currently in pre-alpha development, making it unstable for production use
-Requires peer dependency on Zod v4 for schema validation, adding complexity to setup
-May be over-engineered for simple context provision scenarios that don't need full MCP protocol

Use Cases

•MCP 服务器开发过程中的功能验证和调试测试
•集成 MCP 服务器到应用前的接口兼容性检查
•MCP 协议实现的教学演示和原型验证

•Building MCP servers that provide tools, resources, and prompts to LLM applications
