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.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
