Lexware

Connects Claude to the Lexware Office API for German small business accounting. You get 64 tools across invoices, credit notes, contacts, articles, vouchers, and payments. The server ships with six entry points so you can load just sales, bookkeeping, or contacts if you're hitting tool limits. Create and finalize invoices, pursue documents through workflows, upload voucher files, manage contacts and articles, download PDFs. Ships with automatic rate limiting and webhook signature verification. This is a community project, not official Lexware software, and write operations touch real accounting data. Good fit if you're automating German invoice workflows or building accounting assistants that need structured access to Lexware Office beyond their web UI.
