Connect Lexware Office (Accounting & Invoicing) MCP to Mastra AI
Create your Vinkius account to connect Lexware Office (Accounting & Invoicing) to Mastra AI and route execution through our secure gateway. The platform manages server hosting, runtime updates, and security layers. Configuration requires no manual server provisioning.
Multi-step billing workflows with Mastra AI.
The `list_invoices` and `get_invoice` tools allow you to build automated follow-up workflows for overdue payments. Mastra AI handles the conditional logic, routing actions based on invoice status. If a payment is marked unpaid, the workflow branches to check payment terms before alerting staff.
Automated ledger reconciliation loops.
The `list_vouchers` and `list_credit_notes` tools let your system automate monthly reconciliation loops. Mastra manages the state transitions, pausing the workflow for human approval if a discrepancy is found. This ensures your ledger remains accurate without manual oversight.
Resilient contact creation via MCP Server.
The `create_contact` tool lets you sync external CRM data directly into your Lexoffice bookkeeping system. Wrapping this in a Mastra workflow ensures that every customer record is written with strict error handling. The framework retries failed requests automatically to prevent duplicate records.
