CAIN-42 MCPGateAttack lab
Six transfers on the public demo killswitch (an isolated copy; it never touches production).
3 attacks 3 controls live: nothing pre-recorded
- Pick a preset. Red ones are attacks, green ones are honest requests that must still work.
- Tamper. Choose any field and drop it, null it, change its type, upper-case it, flip one character, or add a field the product never asked for.
- Send and read the real reply, or run every preset and watch the scoreboard fill.
