Agent Live Code Integration with MCP Server

The `send_whatsapp_message` tool allows the AI agent to call live APIs and inject real data directly into your code base. You're not getting mock responses; you get actual, usable results from calling this MCP Server. This means when your developer is writing a function that needs to confirm an action via WhatsApp, the agent handles the API call using `send_whatsapp_message` and writes the result directly into the file.

Coding Workflows with WhatsApp Message Sender

When you need your code to react to communication needs, use `send_whatsapp_message`. The agent mode lets the AI construct working API calls—specifying the target number and message body—right where you're coding. It changes how you think about context. Instead of writing placeholder comments for communication steps, the agent generates functional code using the MCP Server to handle outbound messages.

Cursor Agent Mode and Messaging Tools

You configure the `send_whatsapp_message` tool in your project scope or globally via `.cursor/mcp.json`. The AI then uses this declared capability when generating code that requires a WhatsApp notification. This keeps all dependencies—your local code, the MCP Server definition, and the live API calls—contained within your development environment.
