Send Text Messages via MCP Server

The `send_text_message` tool lets you send a free-form conversation message. You just provide the E.164 phone number and the text body, and your AI client sends it to WhatsApp Business. Since this result streams directly into the UI, users see the message appear in real time, not after waiting for a loading spinner.

Send Media Messages via MCP Server

Use `send_media_message` to get images, videos, documents, or audio files into WhatsApp Business. You only need the recipient number and an absolute file URL. Your agent client handles this by streaming the result, so the user sees confirmation of the media send instantly as it happens.

Send Interactive Reply Buttons via MCP Server

The `send_quick_reply_buttons` tool lets you pre-load up to three quick-reply buttons. You define the explanation text and a comma-separated list of button labels. This interaction is displayed live in your front end, letting users see the message block populate instantly when the AI client executes this MCP Server call.

Setup guide

Set up WhatsApp Business MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all WhatsApp Business tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent WhatsApp Business transactions",
});

console.log(text);
await mcpClient.close();
