Simulate Orders with the MCP Server

Need to test how a cart looks before hitting live data? You can simulate entire checkout sequences. Cascade handles this by running `simulate_order` and then using `simulate_payment`. This lets you calculate shipping costs and validate payments without touching real customer info. It's perfect for testing edge cases in your CI/CD pipeline or just confirming business logic. The sequence is automated: it builds a mock cart, gets the final totals, and reports back if the payment simulation succeeded.

Manage Customer Profiles with Windsurf

Want to check what data a user has on file? Your agent can call `get_client_profile` to pull details. From there, you'll know exactly if they need an updated shipping address or not. If the profile is missing something, Cascade handles it instantly with `create_address`. You just set the goal—like 'make sure John has a billing address on file'—and Windsurf figures out the two steps needed to make it happen.

Apply Coupons and Get Cart Details

Running into coupon logic errors? Use `get_orderform` first to see the baseline cart details. Then, trigger `add_coupon` with a specific code. This shows you exactly how the discount is applied to the total. It’s quick and reliable. You get a real-time view of the updated cart totals right in your IDE context. This mechanism helps verify that sales promotions calculate correctly before deployment.
