About MCP Lexware Office
The server uses Code Mode: instead of one MCP tool per API endpoint, it exposes two tools — search to explore a curated Lexware API catalog and execute to run constrained, sandboxed API workflows. This keeps the tool surface small while covering the whole API, including pagination, aggregation, and multi-step reporting in a single call.
Features
Broad Lexware Office API coverage for read and write workflows
Sales documents: invoices, quotations, order confirmations, credit notes, delivery notes, dunning notices, and down-payment invoices
Contact management: create, read, and update customers and vendors
Bookkeeping: vouchers, posting categories, payments, and file uploads
Reference data: profile, countries, print layouts, payment conditions, recurring templates
Webhooks: create, list, inspect, and delete event subscriptions
Read-only by default: writes require explicit opt-in via environment variable
