OpenOCD Debugger runs on your own machine — the client starts it, so there is no endpoint to ping. 126 installs a week from pypi. Last commit 2 Jul 2026.
Debug microcontrollers via OpenOCD: flash, breakpoints, memory, registers and variables.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
