Perplexity

Terminal-Driven Product Invoice Emission

The `emit_nfe` tool issues Brazilian product invoices directly from your command-line interface via the MCP server. Claude Code executes this tool to trigger live or sandbox emissions without opening a browser or an IDE. You can pipe JSON payloads from local files directly into the tool. The CLI client processes the SEFAZ response, allowing you to build lightweight shell scripts for automated billing runs.

Headless Service Invoice Generation

The `emit_nfse` tool generates municipal service invoices via the command line. Claude Code calls this tool to handle complex city-level tax structures during automated cron jobs or deployment scripts. This headless execution makes it simple to integrate service billing into your CI/CD pipelines. You can trigger emissions after successful subscription renewals without writing backend glue code.

CLI Document Verification and Cancellation

The `consult_document` tool checks the status of any invoice directly inside your terminal session. Claude Code runs this to inspect SEFAZ processing times and return raw tax data. If a transaction fails validation or needs a rollback, you can invoke `cancel_document` with a justification string. You can also run `download_xml` to pipe the authorized fiscal XML directly into other CLI utilities.

Run the command `claude mcp add --transport http focus-nfe -- ` in your terminal. This registers the server in your local config, allowing Claude Code to access all five tax tools instantly.

Yes. You can run Claude Code in non-interactive mode within GitHub Actions or GitLab CI. It uses `emit_nfe` or `emit_nfse` to generate test invoices during deployment validation stages.

You can pipe a list of invoice IDs into Claude Code. It iterates through the list, calling `consult_document` for each one and outputting the raw JSON status to your terminal or a log file.

Ask Claude Code to download a specific document. It executes `download_xml` and saves the raw XML payload directly to your current working directory, ready for archiving.

All tax documents and API credentials remain on your local machine or secure CI environment. The MCP server processes requests ephemerally, ensuring no tax data is cached on third-party servers.
