search_voices
AI agents call search_voices to retrieve information from ElevenLabs MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search functions are typically read operations that query and return data without modifying state. No side effects are implied. While the description is uninformative, the name clearly indicates a search/retrieval function, and the broader context of an audio API suggests this searches available voices in ElevenLabs' voice library.
From the tool's definition Tool name 'search_voices' indicates a query operation that retrieves voice data. The empty description provides no contradictory evidence.
