McuBuddy

Overview

McuBuddy is an MCP server that brings AI-native debugging and observability to microcontroller development. It exposes probes, symbols, RTOS introspection, logs, and build tools as MCP tools, letting AI assistants help you diagnose firmware issues and understand embedded system behavior in real time.

The server runs locally on your machine via uvx McuBuddy, communicating with your MCP client over stdio. No authentication is needed. Version v0.5.1 is available now under the MIT license, with full source code at cunjun/McuBuddy on GitHub.

McuBuddy appears in the Development category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP-compatible clients. If you maintain this project, you can claim this listing to verify ownership and keep it up to date.
