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 LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Correios do Brazil tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
