MadTaco runs on your own machine — the client starts it, so there is no endpoint to ping. 96 installs a week from npm. Last commit 11 Jul 2026.
Verification and trust checks for AI agents: validate, screen, propose, accounts, usage.
Today is the operative word: we check MadTaco every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
