Get community participants.
AI agents call whatsapp_get_community_participants to retrieve information from WSAPI WhatsApp MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs data retrieval (Read category). While it doesn't modify data, the severity is elevated to medium rather than low because retrieved participant information could include personal contact details, phone numbers, or identifiers that could be misused for social engineering, harassment, or privacy violations if an AI agent extracts and exfiltrates this information without authorization.
From the tool's definition Tool name 'whatsapp_get_community_participants' combined with description 'Get community participants' indicates a retrieval operation that queries and returns a list of participants in a WhatsApp community without modifying data.
