list_invoices
AI agents call list_invoices to retrieve information from Clockify Time Tracking without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_' prefix conventionally indicates a query or retrieval operation that returns data without side effects. No description is provided, which slightly lowers confidence, but the naming pattern and the presence of other write/destructive operations (add_invoice_payment, change_invoice_status) on the same server confirm this tool performs read-only retrieval of invoice data.
From the tool's definition Tool name 'list_invoices' and context of a time-tracking system indicate retrieval of invoice records without modification.
