Fldigi MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 116 installs a week from pypi. Last commit 29 Sep 2026.
Control fldigi (amateur-radio digital modes) over XML-RPC: modem, frequency, rig, log, transmit.

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.
raw = subprocess.run(cmd, capture_output=True, text=True, timeout=5).stdout
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
