The search operation is a read-only query that returns matching results. While the data being searched (supplier invoices) is financial in nature, the tool itself only performs retrieval and does not move money, commit financial obligations, or have destructive effects.
From the tool's definition 'Search incoming (supplier) invoices by date range' - the word 'search' and 'by date range' indicate retrieval and querying of data without modification or deletion.
