Windsurf: Autonomous WhatsApp Message Sender

The `send_whatsapp_message` tool lets your AI client talk to customers directly. It takes the destination number in E.164 format and the message body you provide. When Cascade builds a multi-step goal, it can plan for communication failures. If the initial data fetch fails, Windsurf's agent can automatically attempt sending an error alert via `send_whatsapp_message` to a support line.

MCP Server: Integrating WhatsApp into Multi-Step Goals

Your agent needs to update users after processing data. Use `send_whatsapp_message` to send a confirmation text using the Meta Cloud API. You just supply the target phone number and the status message. This ensures that complex workflows don't stall out waiting for human intervention. Windsurf can complete an entire sales cycle, from lead qualification to final notification via WhatsApp.

Automating Customer Alerts with WhatsApp Message Sender

Need your system to alert users about a critical status change? The `send_whatsapp_message` tool sends the text directly. Remember, you must provide the E.164 phone number and the message body for it to work. This is crucial for background processes. When Windsurf runs an overnight data job, it can immediately notify stakeholders of success or failure via WhatsApp.

Common questions about WhatsApp Message Sender MCP in Windsurf

You define the goal for Cascade, and it figures out the steps. Simply give it a prompt like 'Notify user X of the order status.' The agent will recognize that `send_whatsapp_message` is needed, grab the required number and text, and run the operation.

Yes. If the Meta API fails to send a message—maybe it's outside the 24-hour window—Cascade captures that error context. It then lets you adjust the workflow or try an alternative communication channel.

This server handles two primary pieces of information: the destination phone number (E.164 format) and the text message body content.

You'll need pre-approved Meta API templates if you're sending messages outside the 24-hour service window. The tool documentation notes this requirement, so always check your template status before running a multi-step goal.

You connect it through the MCP Servers UI. Once connected, Cascade auto-discovers the `send_whatsapp_message` tool and makes it available whenever your defined goals require external communication.
