A developer experienced production issues after their CI pipeline, which mocked Stripe's API, passed. The mock only verified the API's shape, not its lifecycle, leading to a bug where a PaymentIntent ID was not stored correctly. To prevent this, the developer implemented FetchSandbox's MCP (Mocked Cloud Provider) locally and in CI to test the full payment flow, including webhooks and state transitions, ensuring that code changes by AI agents are validated before deployment. AI
