What is the WhatsApp Message Sender MCP Server?

We refused to build a complex conversational chatbot system that forces you into a specific workflow. Instead, this MCP server provides a surgical, zero-trust bridge: just sending text messages via WhatsApp.

Your AI agent gains the immediate, zero-friction ability to drop status updates, payment confirmations, or emergency alerts straight to any WhatsApp user, bridging the gap between your systems and the most popular messaging app in the world.

The Superpowers

Direct Customer Reach: When an agent finishes a task (like processing an order or analyzing a report), it can immediately ping the user directly on WhatsApp.
Zero-Bloat Integration: No massive SDKs. It uses the direct REST API endpoint (/messages). You only need your Meta Phone Number ID and Access Token.
Absolute Containment: Because this is strictly a sending tool using the official Meta Cloud API, the agent cannot read your WhatsApp inbox, cannot snoop on replies, and cannot alter your Business Manager settings. It is a secure, pure one-way megaphone.

Built-in capabilities (1)

send_whatsapp_message

Provide the destination phone number in E.164 format WITHOUT the plus sign (e.g., 5511999999999 for Brazil) in the "to" parameter, and the text in the "body" parameter. Note: Sending to users outside of the 24-hour service window requires pre-approved templates on the Meta API, otherwise it may fail. Send a text message directly to a WhatsApp number using the Meta Cloud API

FAQ

Frequently asked questions

Can the agent read incoming WhatsApp replies with this?

No. This MCP utilizes the REST API strictly for creating new messages. It does not configure or expose incoming webhooks, meaning it acts strictly as a one-way notification megaphone. It cannot see your customer's replies.

Why are some messages failing to send?

The Meta WhatsApp Cloud API has a strict 24-hour service window. If you are sending a free-form text message to a user who hasn't messaged you in the last 24 hours, the API will block it unless you use a pre-approved Message Template. Ensure you are within the 24-hour window for free-form replies.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
