The "verify what happens after the 200 OK" framing is the actual gap for me — most of my integration bugs live in retries and webhook ordering, not the happy path. Two things I'd want to pin down before wiring it into a Claude Code loop: when I connect over MCP, does the failure library and my recorded scenarios live locally per-project or in your cloud, and can I pin a specific failure (say a Stripe webhook-out-of-order case) so a CI run replays it deterministically instead of re-deriving it each run? Determinism is what decides whether I'd gate a merge on it.
