How to Use the Vonage MCP in Vercel AI SDK

Q: How do I check my Vonage account balance using Vercel AI SDK?

Call the getaccountbalance tool. It returns your current account credit balance, allowing you to show the user real-time spending data in your UI.

Q: Can I send WhatsApp messages with Vonage using Vercel AI SDK?

Yes. The sendwhatsappmessage tool sends a message via the Vonage Messages API. It requires you to provide a verified WhatsApp Business Number as the sender.

Q: What happens if I need to update a virtual number's webhook?

Use updatenumberwebhook. You just pass the E.164 formatted number, and the client updates the inbound SMS callback URL for that virtual number.

Q: How does Vonage handle 2FA verification with Vercel AI SDK?

The process starts by calling startverification with a target number. The user gets an OTP, and your agent client then uses checkverificationcode to confirm it.

Perplexity

Send messages across multiple channels.

The `send_sms` tool sends an outbound SMS message if you provide a sender name and E.164 formatted target number. You can also send WhatsApp via `send_whatsapp_message` or Viber using `send_viber_message`. These tools handle the core messaging operations. This lets your AI client immediately trigger user notifications, like password resets or alerts, directly from a button click in your frontend.

Manage identity verification flows.

To verify a user's identity, start the process with `start_verification`, giving it the target number and brand name. Once initiated, you check if they submitted the correct code using `check_verification_code`. This sequence builds a full 2FA lifecycle. If verification fails or needs to be aborted, the client handles that logic easily by calling `cancel_verification_request`.

Check Vonage account status.

You need to know if you have credit before sending messages. The `get_account_balance` tool retrieves your current Vonage account credit balance instantly. This is a simple check that prevents failed deployments. Additionally, the client uses `get_country_pricing` when it needs to provide an ISO 3166-1 alpha-2 country code for outbound SMS pricing.

Setup guide

Set up Vonage 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 Vonage 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 Vonage transactions",
});

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