List chat rooms where the user is a participant.
AI agents call list_my_chats to retrieve information from Thenvoi 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 chat rooms for the user—a read-only operation. No data is created, modified, deleted, or executed. The blast radius is minimal as it only exposes information the user already has access to via their own participation.
From the tool's definition Tool name 'list_my_chats' and description 'List chat rooms where the user is a participant' indicate a retrieval operation with no modification or side effects.
