Overview

A Model Context Protocol server that enables LLMs to perform embedded debugging via probe-rs. It supports ARM Cortex-M and RISC-V targets using J-Link, ST-Link, and other debug probes. The tool acts as an MCP endpoint, allowing AI agents to read/write memory, set breakpoints, and control execution.

Use cases

• Debug embedded firmware through natural language commands
• Automate flash, reset, and register inspection with LLMs
• Integrate probe-controlled testing into AI-assisted development pipelines

Pros

• Open source with 99 stars, community-backed
• Supports multiple architectures (ARM Cortex-M, RISC-V) and common probes
• Written in Rust for performance and reliability

Cons

• Requires physical hardware and probe connected to a host
• Limited to debug probes supported by probe-rs (not universal)
• Setup requires Rust toolchain and knowledge of MCP configuration
