Azure API管理MCP服务器：企业级API服务的MCP化 🏢⚡
"运筹帷幄，决胜千里" - 在云原生时代，API就是企业的数字化神经系统，而MCP则是让这个系统更加智能的关键！
想象一下：你的企业有数百个API服务，分布在不同的系统中，每个API都有自己的文档、安全策略和使用限制。如果能够通过MCP协议，将这些API统一包装成智能工具，让AI系统能够理解并调用它们，会是什么样的体验？这就是我们要构建的Azure API管理MCP服务器的威力所在！
🌟 项目愿景
设想这样的企业场景：
- 🔧 API即工具：将REST API转换为MCP工具，让AI能直接调用
- 🛡️ 统一安全管理：通过Azure APIM统一处理认证、授权和限流
- 📊 智能监控：实时监控API使用情况和性能指标
- 🤖 AI友好：为AI系统提供语义化的API描述和调用方式
- 🔄 动态配置：支持热更新API配置，无需重启服务
这就是我们要打造的下一代企业API管理平台！
🏗️ 系统架构：企业级API的智能化改造
让我们用一个形象的比喻来理解这个系统。想象一个现代化的企业总部大楼：
