### Description (declared)

# lw-ble-mcp — 轻量级蓝牙调试 MCP Server 
 
**lw-ble-mcp** 是一个面向 AI Agent 的轻量级蓝牙低功耗（BLE）调试 MCP 服务器。基于 MCP Python SDK（FastMCP）与 bleak 构建，以 `lw_ble_*` 前缀提供 21 个工具：扫描、连接、GATT 读写、描述符访问、MTU 查询、通知订阅、一键设备侦查（`lw_ble_dump`）与引擎诊断（`lw_ble_engine_status`）。 
 
核心特性：连接永不挂死（全部原生调用在专用 I/O 事件循环上运行，带硬超时）· 下划线工具名兼容广泛 MCP 客户端 · 分层测试体系（76 个用例，含真机回环验证）。 
 
>工具标识统一使用 `lw_ble_` 前缀与下划线风格：`lw`（lightweight，轻量级）沿用嵌入式领域惯例（如 lwIP），`ble` 明确标注协议为蓝牙低功耗。命名刻意保持独立命名空间，避免与常见 `ble_*` 工具名冲突。 
 
**lw-ble-mcp** is a lightweight Bluetooth Low Energy (BLE) debug MCP server for AI agents. Built on the MCP Python SDK (FastMCP) and bleak, it exposes 21 tools under the `lw_ble_*` prefix: scan, connect, GATT read/write, descriptor access, MTU query, notification subscription, one-shot device recon (`lw_ble_dump`), and engine diagnostics (`lw_ble_engine_status`). 
 
Key features: connect never hangs (all native calls run on a dedicated I/O event loop with hard timeouts) · underscore tool names for broad MCP-client compatibility · a layered test suite (76 cases, including real-hardware echo-loop verification). 
 
## 设计要点 
 
| 关注点 | 实现 | 
|---|---| 
| 连接边界保护 | 全部 bleak 调用跑在**独立线程的专用事件循环**上，外层用 `asyncio.wait_for` 包裹，卡死也能真正超时返回 | 
| 客户端兼容性 | 工具名一律用下划线（`lw_ble_scan`），避免点号工具名与部分 MCP 网关冲突 | 
| 错误可诊断 | 区分 `entity_not_found` / `operation_timeout` / `link_not_connected` / `internal_error` 等错误码 | 
| 依赖 | 使用最新的 bleak 3.x | 
 
## 安装 
 
```powershell 
pip install -r requirements.txt 
``` 
 
## 在 Cursor 中配置 
 
编辑全局 `C:\Users\Administrator\.cursor\mcp.json`： 
 
```json 
{ 
  "mcpServers": { 
    "ble": { 
      "type": "stdio", 
      "command": "D:/DevTools/Python/v314/python.exe", 
      "args": ["-m", "ble_mcp"] 
    } 
  } 
} 
``` 
 
把 `command` 替换为你实际的 python 路径。配置后重启 Cursor。 
 
## 工具列表 
 
### 扫描 
 
| 工具 | 说明 | 
|---|---| 
| `lw_ble_scan` | 启动后台扫描（支持 name_filter / service_uuid），返回 scan_id | 
| `lw_ble_scan_poll` | 非阻塞获取扫描结果 | 
| `lw_ble_scan_stop` | 提前停止扫描 | 
| `lw_ble_scan_list` | 列出所有扫描 |
