Perplexity

Fix billing mistakes directly in Claude Desktop

The `send_cc_e` tool lets you issue Correction Letters (CC-e) for incorrect invoices directly from your chat. If things go wrong or you make another typo, you can run `cancel_cc_e` to pull it back. Your agent handles the payload formatting so you don't have to manually edit raw XML tags. This MCP Server connects your desktop client straight to the Focus NFe API. You no longer have to log into a separate tax portal just to fix a minor address typo on a recent invoice.

Pull XMLs and DANFE PDFs without leaving chat

Use `download_nfe_danfe` to get PDFs of your invoices instantly. Your agent can also run `download_nfe_xml` or `download_event_xml` to grab the raw data files you need for tax compliance. The files save to your local machine because Claude Desktop runs this MCP Server locally. You get the exact fiscal records you need without manually searching through email attachments.

Audit your fiscal history with your agent

Keep track of your billing by running `list_nfe_by_period` to check invoices over a specific timeframe. You can also monitor incoming and outgoing services with `list_nfse_emitted` and `list_nfse_received` to keep your books balanced. Your agent analyzes the JSON responses to find missing receipts or flag anomalies. It makes auditing your business finances as simple as asking a quick question in your chat box.
