Show Live Call Data in Your App

When you call `list_calls`, the results stream instantly to the user interface. They see recent Twilio calls pop up on screen as your agent fetches them. You can also get immediate feedback by running `list_messages`. This lets your frontend display incoming or outgoing SMS records live, without needing a loading spinner.

Manage Voice Calls in Real-Time

Need to end an active voice conversation? Use `cancel_active_call` and the user sees confirmation immediately. You can also initiate outbound calls using `create_voice_call`, showing the progress of the call setup right in your app's UI. This live data feed makes building communication tools feel native, letting users watch Twilio actions happen as they execute.

Fetch and Display Account Records

`get_usage_records` retrieves billing stats, which you can display in a dashboard that updates instantly. Furthermore, `list_phone_numbers` pulls all owned numbers, letting your client build an interactive inventory view. Every data retrieval from this MCP Server streams to your UI. This makes building sophisticated Twilio-powered dashboards feel incredibly fast and responsive.

Setup guide

Set up Twilio 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 Twilio 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 Twilio transactions",
});

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