Sync new WhatsApp messages from relay. Call this before reading messages to get the latest.
AI agents call whatsapp_sync to retrieve information from VIDA AI 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 a data retrieval and synchronization function. While it interacts with an external relay service, it only fetches incoming messages without side effects. The purpose is to ensure the latest messages are available for the read_messages tool. No data is modified, deleted, or executed. The blast radius of misuse is minimal - at worst, an agent could repeatedly sync, causing minor API overhead.
From the tool's definition Tool description states 'Sync new WhatsApp messages from relay' - a synchronization operation that retrieves/fetches data without modifying, deleting, or executing external commands. It prepares data for reading.
