DG-MCP
The DG-MCP server lets you control DG-Lab Coyote 2.0/3.0 electrical stimulation devices via Bluetooth through any MCP-compatible LLM client (e.g., Claude Desktop).
Device Discovery & Connection
scan— Discover nearby Coyote devices (address, name, version)connect— Connect to a device via BLE addressdisconnect— Disconnect from the current deviceget_status— Query connection status, strength levels, active waveform, and battery
Channel Control
start— Start a channel (A/B) with initial strength (0–10) and a waveform (breath, tide, pulse_low, pulse_mid, pulse_high, tap)stop— Stop one or both channelsadjust_strength— Incrementally adjust a running channel's strength (±10 per step)change_wave— Switch waveform on a running channel without changing strengthburst— Briefly spike a channel to a target strength for 100–5000ms, then auto-returnemergency_stop— Immediately zero all strength and stop all waveforms
Waveform Management
list_waveforms— List all available waveforms (built-in + imported)load_waveforms— Import waveforms from.pulsefiles or.ziparchives at runtimedesign_wave— Create custom waveforms using composable segments:ramp(linear change),hold(constant),pulse(on/off beats),silence(quiet interval); optionally play immediately on a channel
Utility
timer— Set a countdown timer (1–3600s) for deferred follow-up actions within a conversation flow
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@DG-MCPScan for nearby Coyote devices."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
DG-MCP
让 Claude Desktop 等 MCP 客户端直接控制 DG-Lab 郊狼 2.0 / 3.0
中文 | English
这是什么
DG-MCP 把郊狼设备暴露成一组 Model Context Protocol 工具,让任何 MCP 兼容的 LLM 客户端(Claude Desktop、Continue 等)能通过蓝牙直接驱动你的设备——scan / connect / start / stop / adjust_strength / change_wave / burst / design_wave / emergency_stop 全套都是普通的工具调用。
跑在 Node.js 里,通过 stdio 跟客户端通信。基于 @dg-kit/* 中台,跟 DG-Agent / DG-Chat 共享一份协议代码。

状态
1.0.0正式版,已发布到 npmv0.1.x 的 Python 实现归档在
archive/0.x-py分支,PyPI 上仍可下载但不再更新
快速开始
安装
不需要预装,npx 直接拉:
npx dg-mcp --version或者全局装:
npm install -g dg-mcpClaude Desktop 配置
打开 Claude Desktop 的配置文件,加入:
{
"mcpServers": {
"dg-lab": {
"command": "npx",
"args": ["-y", "dg-mcp"]
}
}
}要预加载波形包:
{
"mcpServers": {
"dg-lab": {
"command": "npx",
"args": ["-y", "dg-mcp", "--waveforms-dir", "/Users/you/wave-pack"]
}
}
}重启 Claude Desktop,对话框里跟 Claude 说"扫描一下郊狼",它就会调 scan 工具找设备。
CLI 选项
dg-mcp [options]
--waveforms <path> 启动时加载一个 .pulse 或 .zip 文件(可重复)
--waveforms-dir <dir> 加载目录下所有 .pulse / .zip
--library-dir <dir> 用户导入的 / AI 设计的波形持久化到这个目录
--help, -h
--version, -v
环境变量等价:
DG_MCP_WAVEFORMS 冒号分隔的多路径
DG_MCP_WAVEFORMS_DIR 同 --waveforms-dir
DG_MCP_LIBRARY_DIR 同 --library-dir工具列表

| 冷启动通道,一次设强度 + 波形 |
| 停止通道;省略 |
| 相对调整强度(±10/步,5s 内最多 2 次) |
| 不动强度,仅换波形 |
| 短时拉到目标强度后自动回落(5s 内最多 1 次) |

| 立即归零 |
安全
强度量程是 0-200。冷启动工具自动钳制初始强度 ≤10,请从低强度开始
默认软上限是 200;如果你需要更严格的硬限制,让 LLM 客户端策略层加约束
设备物理拨轮可以单独叠加强度——MCP 只是输入源,不是绝对天花板
任何时候说"紧急停止",AI 会调
emergency_stop立即归零
系统要求
Node.js ≥ 20
支持 BLE 的主机(macOS / Linux 走 BlueZ / Windows 配 noble 兼容适配器)
DG-Lab 郊狼 2.0(D-LAB ESTIM…)或 3.0(47L121…)
macOS
首次跑会弹蓝牙权限申请,允许即可。
Linux
noble 需要 BLE 抓包权限:
sudo setcap cap_net_raw+eip $(eval readlink -f $(which node))架构
