JWT runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 25 Feb 2026.
MCP server for JWT decoding and inspection
What the code does
We read the source, 3 d ago · rules 995398eba69f
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.
subprocess.run(["npm", "install"], cwd=str(server_dir), capture_output=True, timeout=60, shell=True)
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
