List all billing records in your VoIPbin account.
AI agents call list_billings to retrieve information from VoIPbin MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing billing records with no side effects. It performs a data lookup operation similar to 'list' or 'get' patterns, which are characteristic of Read category tools. While billing data is sensitive (moderating severity from very low to low), the read-only nature and limited blast radius of viewing existing records keep severity low.
From the tool's definition Tool name 'list_billings' and description 'List all billing records in your VoIPbin account' indicate a read-only query operation that retrieves billing data without modification or execution.
