Frequently asked questions
Can my AI automatically issue an NFS-e for a specific customer?
Yes! Use the issue_service_invoice tool with the Company ID and a JSON payload containing the customer data and service values. Your agent will trigger the issuance process with the relevant municipality.
How do I find the correct IBGE code for a Brazilian city?
You can use the list_cities tool to search for municipalities by name or state. The agent will return the official IBGE codes required for fiscal document validation.
Can I retrieve the download link for an invoice PDF?
Yes! Use the get_service_invoice tool with the unique Invoice ID. Your agent will return the metadata, including official links to download the PDF and XML versions of the document.
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.
