Connects to NFS-e (Nota Fiscal de Serviço) systems for Brazilian businesses. Muse can issue invoices, check status, list past invoices, download PDFs and XML, and cancel invoices when needed.

Example request: "Issue a service invoice for a client in São Paulo and send them the PDF"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Nota Fiscal to help me. It is a free service with an MCP server at https://api.mcp.ai/p_notafiscal. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
