Get WhatsApp chats, optionally filtered and sorted.
AI agents call list_chats to retrieve information from WhatsApp MCP Stream without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves chat metadata from WhatsApp without side effects. It is categorized as Read per the definition 'retrieves or queries data; no side effects'.

From the tool's definition Tool name 'list_chats' and description 'Get WhatsApp chats, optionally filtered and sorted' indicate data retrieval with no modification capability. The verb 'Get' and absence of mutation language (create, delete, update) confirm read-only semantics.
