How to Use the SimpleFatoora MCP in Claude

Q: How can I use SimpleFatoora with Claude Desktop for B2C invoicing?

To create a simplified invoice, your agent calls createsimplifiedinvoice. You just pass the required details—like customer ID and product list—and it handles the ZATCA formatting. It's pretty straightforward to set up locally.

Q: Does SimpleFatoora support credit notes when using Claude Desktop?

Yes, absolutely. You use the createcreditnote tool. This generates a formal document that reduces the amount owed on an invoice, which is key for returns or adjustments.

You just run listcustomers. The tool returns a structured list that your AI client can read immediately. This means you don't have to manually check each account one by one.

You use validateapikey. Your agent sends your current token to this tool, and it immediately tells you if the key is active or expired. This saves a ton of time before you start a large batch of transactions.

Manage all core financial documents.

You can generate different types of invoices. Use `create_simplified_invoice` to handle B2C transactions, or call `create_vat_invoice` when you need a full B2B VAT document. Need to track purchases? You'll use `create_standard_purchase` for standard vendor receipts, and `create_simplified_purchase` for basic ones. The agent manages the tax calculations needed for every type.

Keep your customer data clean.

Need to start a new client? Run `create_customer` to build a record, or use `list_customers` to pull an existing list. If things change, you can update records with `update_customer` or delete them completely using `delete_customer`. If the customer details are wrong, your agent can check the current information first by calling `get_customer`. This keeps the data accurate before any invoicing happens.

Maintain product catalog integrity.

`create_product` lets you add new items to your system. If a product changes, simply call `update_product` with the new specifications. You can also remove obsolete goods using `delete_product`. Before creating anything, it's smart to see what's already there; just run `list_products`. This helps you avoid duplicates or missing tax codes.
