Can the AI perform destructive actions like making a real payment or deleting invoices?

No. The integration focuses strongly on extraction via READ endpoints (e.g. `list_payments`, `list_budgets`, `list_expense_claims`). It is designed to act as an advanced analytical viewing lens allowing you to query, organize, and monitor financial positions without executing operational mutations like transferring money.

How can the AI help me understand a specific expense claim?

You can provide the Expense ID from your `list_expense_claims` search and ask natural questions. The AI will pull the structured data and explain explicitly who submitted the reimbursement, the exact amount, the associated spending currency, and the current processing status, formatting it all into an easily digestible summary.

How deep is the Spendesk token scoped? Is it secure?

The integration is secure. Your Vinkius Agent runs strictly client-side on your PC. It queries the API using the explicit Bearer Token you manage. Spendesk's token access capabilities can also be carefully constrained natively from your Organization's Integration Settings to further enforce least privilege.
