Indexing Communication History for LlamaIndex

The `send_text_message` tool allows you to process and index every free-form text conversation. When your AI client interacts with this MCP Server, the output becomes data that can be added to a vector store. This means you build RAG applications where past WhatsApp Business chats aren't just logs; they're searchable knowledge used to answer new queries.

Retrieving Media Metadata via MCP Server

When the agent calls `send_media_message`, LlamaIndex indexes the associated metadata—the file type, the public URL, and the context of its delivery. You can then query your knowledge base to recall details about past images or documents shared. This moves beyond simple chat history; you retrieve actionable data grounded in actual API interactions.

Tracking Interactive WhatsApp Flows with LlamaIndex

The `send_quick_reply_buttons` tool provides structured interaction points. By indexing the usage of these buttons, your LlamaIndex application tracks which options are most popular or effective in guiding a user through complex business processes. This lets you analyze real-world user behavior from WhatsApp Business interactions and refine your automation strategies.
