Tryx402 runs on your own machine — the client starts it, so there is no endpoint to ping. 133 installs a week from pypi. Last commit 11 Sep 2026.
Budget router over x402: hard budget caps, idempotent paid calls, cost ledger, server-side pricing.

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.
proc = subprocess.run(args, capture_output=True, text=True, timeout=timeout)
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.

This one needs environment variables set before it will start:
