List all active conversation histories
AI agents call list_conversation_histories to retrieve information from Second Opinion MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about existing conversation histories for informational purposes only. It has no side effects, does not modify or destroy data, and does not execute external operations or move money. The blast radius of misuse is minimal—an attacker could gain visibility into conversation metadata but cannot alter or damage the system. This is a standard Read operation.
From the tool's definition 'List all active conversation histories' indicates a query or retrieval operation that returns data without modifying or deleting it.
