Perplexity

Managing New Items via MCP Server

When you call `create_new_item`, your agent doesn't risk silent errors. Because the response is validated against a Pydantic model, if the API returns unexpected data, the agent fails loudly with an error—you know exactly what went wrong. This level of type safety means you can trust that every time a new item record is created, it adheres strictly to your defined schema.

Creating Sales Orders with Pydantic AI

The `create_sales_order` tool lets your agent process orders. The primary benefit here is validation: the entire payload—from customer info to line items—is checked against a defined schema at runtime. This eliminates data corruption risk. If Zoho Inventory sends back an unexpected field, your Pydantic AI setup immediately catches it, keeping your production workflow robust.

Listing All Sales Orders

To get a list of completed orders, the agent calls `list_sales_orders`. The resulting data is automatically validated by Pydantic. This guarantees that every record you process has predictable fields. You can rely on this structured output when feeding Zoho Inventory data into any downstream application or report.
