## 📖 项目简介

`mcp-server-tcp` 是一个基于 Python 3.10+、Model Context Protocol 官方 SDK (`mcp`) 与 `asyncio` 的高性能通用 TCP 协议 MCP 服务端。赋能大语言模型（LLM）与任意 TCP 目标服务、IoT 工业硬件及私有二进制协议（如 Modbus、自定义二进制 RPC）进行全双工收发与自动化联调。

## ✨ 核心特性

- 🎯 **双向通信全能**：不仅支持作为 TCP 客户端主动向外连接，还支持动态启动本地 **Mock Server** 被动捕获外部设备连入并模拟应答；
- ⚡ **原生全双工并发**：采用读写锁分离架构（ADR-0005），长轮询等待接收（`recv`）时绝不阻塞并发指令下发（`send`）；
- 🧩 **原子定界与半包保全**：独创软超时机制（Soft Timeout），定界符未达时不破坏报文流，无损保留半包缓冲（Drain Buffer）静默等待后续拼接；内置 10MB 缓冲区防 OOM 熔断门禁；
- 🛡️ **探针并发平滑门禁**：端口批量扫描限制单次上限 128 个端口，内置 32 并发信号量，彻底规避系统套接字句柄耗尽崩溃；
- 🔍 **内存环形流量审计**：每个连接独享 100 条环形缓冲区（Traffic Ring Buffer），提供时间戳、传输方向及 Hex/文本快照，零磁盘污染；支持标准 MCP Resource 挂载读取；
- 🔒 **工业级安全防线**：默认拦截云厂商元数据（`169.254.169.254`）及高危保留网段，Mock Server 监听绑定受分级安全策略管辖，全方位防范 SSRF 攻击；
- 🚀 **开箱即用与容器分发**：支持 `uvx` 零配置即开即用，同时发布多架构容器镜像至 GitHub Packages (`ghcr.io`)。
