jlink-mcp vs DebugMCP

jlink-mcp: jlink-mcp is an MCP server that enables AI assistants to debug embedded hardware using SEGGER J-Link probes. It provides a rich set of tools for LLMs to read device state, flash firmware, stream logs, and diagnose crashes on ARM Cortex-M targets.; DebugMCP: DebugMCP empowers AI coding agents with full control over the VS Code debugger, allowing them to autonomously set breakpoints, step through code, inspect variables, and evaluate expressions. It runs 100% locally, requires zero configuration, and works seamlessly with any MCP-compatible AI assistant across various programming languages.
