List all conversation flows.
AI agents call retell_list_conversation_flows to retrieve information from Retell AI MCP Server 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 existing conversation flows without creating, modifying, deleting, or executing any actions. It is a pure read operation with minimal security risk—the only potential exposure is information disclosure about configured conversation flows, which is low severity.
From the tool's definition Tool name 'retell_list_conversation_flows' and description 'List all conversation flows' indicate a retrieval/query operation with no data modification or side effects.
