SimpleFatoora MCP. Automate ZATCA-compliant invoicing from chat.

Listen up. If you're dealing with billing in Saudi Arabia, you need this SimpleFatoora server hooked up to your agent. It handles all the complicated stuff—making sure every invoice is 100% ZATCA compliant. Your agent gets programmatic access to generate six different types of invoices and keeps track of every detail: who bought it, what was sold, and how much tax applies.

Before running anything, your agent first checks things out. You'll use validate_api_key to confirm the API key is valid and active. It's also smart enough that you can run check_simplefatoora_status right away; that tells you if the whole SimpleFatoora connection is up and working before you try to send a single dollar.

Generating Compliant Invoices. This server lets your agent create specific documents required by law. To handle retail sales, it'll use create_simplified_invoice for B2C simplified billing. For registered businesses doing VAT transactions, the agent uses create_vat_invoice to generate a compliant B2B VAT invoice. If you're dealing with purchases, it gives you two options: running create_standard_purchase for full-detail purchase invoices or using create_simplified_purchase if that’s what fits your needs.

You don't just create invoices; you adjust them too. When a customer returns something, the agent runs create_credit_note, generating a compliant credit note linked right to the original invoice. If there's an overpayment or some other adjustment needed, it uses create_debit_note to generate that official debit note.

Managing Customer Profiles. You can build and maintain your entire customer database using these tools. To start someone new, you run create_customer. Need the details on a specific client? Use get_customer with their ID; otherwise, you can pull up multiple clients by running list_customers, often filtering them by things like VAT number.

If an address changes or they get a tax update, you just call update_customer. When a customer account is totally defunct and needs to be wiped from the system records, you use delete_customer.

Handling Product Catalogs. The agent keeps your master data clean too. To add new services or items, it uses create_product; if you need details on an existing item, run get_product with the code or ID. Want to see everything you've sold? list_products pulls a complete list of all available products.

If the price goes up or the VAT rate changes, you use update_product. And if a product line is dead and needs removing entirely from your catalog records, it uses delete_product.

Checking Records. You don't have to guess what happened with an invoice number. get_invoice pulls up all the data and current status for any existing invoice you provide. If you need a full history of everything generated in the account, run list_invoices to get a paginated list of every invoice.

You can also call list_products again just to verify what's sitting in your catalog.

This setup gives your agent total control over the entire financial lifecycle. You manage the client data, you keep the product codes fresh, and you generate every single document—from the initial B2C invoice to the final debit note—all while staying compliant with ZATCA regulations. It’s a full-stack solution; it's built for real business use.
