Frequently asked questions
How can I calculate the shipping price for a specific package?
Use the calculate_prices tool. You will need to provide the origin and destination ZIP codes, weight, dimensions, and the service code (e.g., 04014 for SEDEX).
Can I check the delivery deadline between two Brazilian cities?
Yes! The estimate_delivery_time tool allows you to input the service code and both ZIP codes to receive the estimated delivery time in working days.
Is it possible to find an address using only the ZIP code (CEP)?
Absolutely. Use the consult_cep tool with the 8-digit ZIP code to retrieve the street name, neighborhood, city, and state 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.
