Perplexity

Run large-scale audits with Google ADK

The `list_vouchers` tool feeds a continuous stream of your company's expenses and invoices directly to Gemini. Because the model handles massive token windows, you can dump months of voucher history into a single prompt for deep anomaly detection. You can cross-reference this financial stream with raw purchase logs stored in BigQuery. The agent identifies missing receipts and highlights tax discrepancies without manual spreadsheet work.

Monitor invoice lifecycles in real time

The `list_invoices` tool retrieves your complete billing history in a structured, paginated format. Your Gemini agent parses this ledger to track unpaid balances and flag accounts that have slipped into dunning status. This lets you run automated revenue reconciliation using this MCP directly inside your Google Cloud environment. It pulls tax amounts and net totals directly from your live account.

Sync contacts with Google Cloud databases

The `list_contacts` tool exports your entire customer and vendor directory from Lexware Office. The agent uses this list to clean up duplicate entries and match contacts against internal CRM systems. When a new client signs up, the agent calls `create_contact` to set up the profile with standardized names and roles. This keeps your accounting data clean from day one.
