Summary
A platform-hosted connector for issuing and managing Brazilian NFS-e (service invoices) through conversation, no nfe.io account required. You connect your CNPJ and A1 certificate, then ask your agent to issue invoices, query them, download PDFs and XML files, or cancel them. It's read-only and runs on a prepaid credit model. Works over streamable HTTP so it plugs into Claude Desktop, Cursor, VS Code, or any MCP-over-HTTP client. Authentication is handled via magic link. Useful if you're already working in an AI coding assistant and need to handle Brazilian fiscal compliance without context-switching to a separate invoicing platform.
Fastest browser for AI agents to run web automation tasks, always free.
