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 AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call NFe.io tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
