embedded-debugger-mcp

Was er kann

A Rust MCP server for debugging microcontrollers from an AI assistant. It drives a hardware debug probe such as ST-Link, J-Link or DAPLink through probe-rs, or connects to a running OpenOCD over the GDB remote protocol, behind one tool set. Tools cover finding probes, connecting to a target, controlling the core, reading and writing memory, breakpoints, flashing firmware, RTT communication, and crash diagnosis through fault analysis and exception unwinding. It is built from source with Cargo, and the repository also ships a small CLI and a skill for Codex and Claude Code. The author reports testing on real ESP32-S3 hardware.
