openocd-mcp
Provides tools for debugging and flashing firmware on Arm-based microcontrollers by integrating with OpenOCD and GDB, allowing for project management and real-time status monitoring.
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., "@openocd-mcpflash the firmware using the STM32 configuration"
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.
openocd-mcp
基于 fastmcp 的 OpenOCD 调试 MCP 服务,复用项目中的 .vscode/launch.json 作为调试目标来源。
当前阶段(MVP)
已实现:项目切换、调试目标刷新、一次性烧录、调试会话启动/停止、GDB 命令执行、状态查询。
未实现:RTT 相关能力(已拆分到独立文档)。
使用 uv 运行
uv sync
uv run openocd-mcp --openocd-path openocd --gdb-path arm-none-eabi-gdb如果直接运行:
uv run openocd-mcp服务会自动读取当前目录 config.json(若存在)中的路径配置。
参数优先级:命令行参数 > 环境变量 > config.json > 内置默认值。
启动为 SSE/HTTP(给本地其他 AI 客户端)
默认是 stdio。
uv run openocd-mcp -sse默认监听:http://127.0.0.1:9000/sse
可自定义:
uv run openocd-mcp -sse --host 127.0.0.1 --port 9000 --path /sse也可通过环境变量配置:
OPENOCD_PATHGDB_PATHOPENOCD_SCRIPTS
VS Code MCP 配置
已提供 .vscode/mcp.json,使用 stdio + uv run openocd-mcp 启动服务。
如需改为 SSE,可使用:
{
"servers": {
"openocd-mcp": {
"type": "sse",
"url": "http://127.0.0.1:9000/sse"
}
},
"inputs": []
