RECOMMEND which concrete provider integrations this app needs, and WHY — the deterministic Step-2 intelligence the web wizard uses, now over MCP. Pass the app `description` + the platform `service_ids` it will use (e.g. ['cart','order']); returns GROUPED, TIERED suggestions (required/recommended/optional) with the default option flagged — e.g. cart/checkout → a payment gateway (REQUIRED; stripe_checkout default, paypal/razorpay offered), customer-facing apps → transactional email, appointments+reminders → sms. Options are drawn ONLY from the LIVE installed manifests, so it can't suggest a provider you don't have. PRESCRIPTIVE complement to build_list_capabilities (which is descriptive): call this so you don't OMIT a needed integration; use build_list_capabilities for a service's exact id + config fields.
