pdfvera MCP server

Lets AI assistants like Claude and Cursor convert documents with pdfvera:

• German PDF invoices into e-invoices: XRechnung 3.0 (UBL and CII) and a ZUGFeRD PDF (EN 16931), checked against the official KoSIT rules, plus a check report. If mandatory data is missing, the assistant asks you for it.

• Brazilian bank statement PDFs (extrato bancário) into OFX, CSV and Excel: OFX for Domínio, Alterdata, Conta Azul or Omie. Files are only written when the entries add up to the balances printed in the statement.

The server runs on your computer. It reads the PDF from your disk, sends it to the pdfvera API with your API key and writes the result files next to the PDF.

Requirements

• A pdfvera plan. The API and this server are included in every plan, with the same monthly quota as the website (Preise, Preços). Checking a PDF without writing files (check_only) is free.

• An API key, created in your pdfvera account (Konto, Conta).

• Node.js 18 or newer (not needed for the Claude Desktop extension).

Install

Claude Code plugin

/plugin marketplace add pdfvera/pdfvera-mcp
/plugin install pdfvera@pdfvera

You are asked for the API key once; it is stored in your system keychain.

Claude Code without the plugin

claude mcp add pdfvera -e PDFVERA_API_KEY=pv_YOUR_KEY -- npx -y pdfvera-mcp@latest

Cursor (~/.cursor/mcp.json) and other MCP clients

{
  "mcpServers": {
    "pdfvera": {
      "command": "npx",
      "args": ["-y", "pdfvera-mcp@latest"],
      "env": { "PDFVERA_API_KEY": "pv_YOUR_KEY" }
    }
  }
}

Claude Desktop: download pdfvera.mcpb, open it and enter the API key.

Tools

Each converted document counts once against the monthly quota. The same PDF again in the same month does not count; check_only never counts.

Example prompts

• "Convert ~/Rechnungen/RE-2026-0042.pdf into an XRechnung. It's an invoice I sent to a public authority."

• "Check whether all PDFs in ~/Rechnungen/November can be turned into e-invoices, without using my quota."

• "Converte o extrato ~/Downloads/extrato-itau-outubro.pdf em OFX para o Domínio."

• "The statement PDF is password protected; the account holder's CPF is 123.456.789-09. Try again."

• "How many conversions do I have left this month?"

Privacy policy

This program stores nothing. It sends the PDF you name and your answers to pdfvera.com over HTTPS and writes the results to your disk. What pdfvera does with uploaded documents is described in the privacy policies: Datenschutzerklärung (invoices) and Política de privacidade (bank statements). In short: invoice PDFs are processed in the EU and not kept; bank statement PDFs sent through the API are never kept. Only a hash of each converted PDF is stored, so the same document is not counted twice. Bank statements that pdfvera's rules cannot read are sent to the Anthropic API to read the entries; Anthropic deletes that data within 30 days and does not train on it.

Troubleshooting

• "No pdfvera API key": set PDFVERA_API_KEY in the server configuration (or the plugin settings) and restart the assistant.

• "The API key is missing, wrong or revoked": create a new key in your pdfvera account.

• "no active plan" / "quota is used up": files need a plan; check_only works without one.

• The assistant doesn't see the tools: check that node --version prints 18 or newer and restart the assistant.

• Not converted, fields missing: the assistant should ask you for the listed fields; you can also answer them on pdfvera.com.
