Frequently asked questions
Can my AI automatically create a ZATCA-compliant VAT invoice for a customer?
Yes! Use the create_vat_invoice tool. Provide the client details and item list, and your agent will generate a compliant ZATCA Phase 2 invoice instantly.
How do I check the stock level for a specific item in Simple Fatoora?
Simply ask the agent to run the list_items action. It will retrieve the current inventory catalog, including stock counts and pricing for all items.
How do I find my Simple Fatoora API Key?
Log in to your Simple Fatoora dashboard, navigate to Settings > API Integration, and you will find your unique secret API Key there.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Simple Fatoora MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
