Generate a unique invoice number
AI agents call generate_invoice_number to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool generates a unique invoice number, which is a read/utility operation that produces a value without moving money, modifying records, or triggering external operations. It has no financial transaction side effects and is essentially a data retrieval/generation utility. Low severity as misuse would only result in an unused invoice number being generated.
