LlamaIndex and MCP Server Integration

Use `send_whatsapp_message` to generate actionable data points that get indexed. The tool sends a text message using the Meta Cloud API, but its output—the confirmation or resulting conversation snippet—becomes searchable. This means your knowledge base grows with real-time interaction data, not just static documents.

Building Searchable Communication Logs

Instead of losing communication records in separate APIs, you index them. When `send_whatsapp_message` is executed, the result gets stored alongside your other knowledge sources. You can query past interactions to find out what was said about a specific product or service months ago.

MCP Server for Data Grounding

The MCP Server helps ground your AI's responses in actual, confirmed events. If an agent needs to know when it last messaged someone, you index the result of `send_whatsapp_message`. It connects live communication actions directly into your vector store for semantic search.
