List all available AI buyer voices.
AI agents call list_voices to retrieve information from Tough Customer MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of available voices, which is a simple data retrieval operation. It has no capability to modify state, execute commands, delete data, or perform financial transactions. The blast radius if misused by an agent is minimal — at worst, an agent learns what voices exist, which is non-sensitive metadata.
From the tool's definition Tool name is 'list_voices' and description states 'List all available AI buyer voices' — a pure read operation that retrieves data without modification or side effects.
