Perplexity

Type-Safe Store Status Management

The agent calls `set_store_online` and `set_store_offline` to modify your store's active state on the Meituan platform. Pydantic AI validates the success payload at runtime to guarantee the store actually changed states. It retrieves metadata with `get_store_info` to verify store IDs before making state changes. Using this MCP connection prevents your script from toggling the wrong storefront due to dirty configuration data.

Validate Order Payloads with Pydantic AI

Your agent executes `confirm_order` and validates the incoming schema immediately. If Meituan alters its JSON structure, the system raises a validation error instead of processing a corrupt order. The agent uses `get_order_detail` to inspect item lists and runs `cancel_order` if schema validation fails. This MCP Server setup ensures your kitchen display system only receives clean, structured data.

Track Shipments and Verify Menu Categories

The agent calls `track_delivery` to monitor rider updates and parses the status fields into strict Python models. You get guaranteed string and float types for coordinates and timestamps. It uses `list_categories` to fetch your active menu structure. This allows your agent to map items to your internal database without manual type casting or parsing errors.
