Frequently asked questions
How can my AI generate ZATCA-compliant invoices?
Simply use the create_invoice tool. Your agent can instantly generate six types of invoices (including B2C and B2B), all fully compliant with ZATCA Phase 2, complete with QR codes, UUIDs, and cryptographic stamps.
Is it possible to programmatically access my client list and VAT numbers?
Yes. By executing the list_customers action, your AI agent can retrieve your entire client registry, including tax identification numbers, addresses, and contact details for seamless CRM integration.
Can I automatically issue credit notes for partial returns?
Absolutely. Ask the agent to use the create_credit_note tool. It will safely generate a ZATCA-compliant credit note linked to the original invoice, adjusting the accounting records automatically.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
