Compatible with every major AI agent and IDE
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)
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

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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
