Apptoto MCP Server Streaming in Vercel AI SDK

Your Vercel AI SDK client calls `list_appointments` to pull the day's schedule directly into a Next.js frontend. The user asks for their agenda, and the UI populates rows of booking data instantly. You avoid the standard loading spinner because the tool results stream straight to the client. Getting specific booking details happens through `get_appointment`. You pass the ID, and the application instantly renders the confirmation status and client notes. Your React components update as the data arrives over the wire.

Live Contact Syncing

Fetching client directories starts with `list_address_books` to locate the right contact group. Your application determines which specific list the user wants to access based on their prompt. The `list_contacts` tool streams names and phone numbers directly into your custom dashboard. This setup works perfectly in Edge Functions, keeping the server footprint small while giving users immediate access to their scheduling database.

Real-Time Message Feeds

Reading two-way communication requires the `list_messages` tool. Your Vue or Svelte frontend requests recent texts sent to a specific client, and the chat history streams right into your message component. Connected schedules appear via `list_calendars`. The user sees exactly which provider schedules are active before attempting to modify any booking workflows.

Setup guide

Set up Apptoto 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 Apptoto 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 Apptoto transactions",
});

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

Common questions about Apptoto MCP in Vercel AI SDK

Call mcpClient.tools() to get the scheduling tools, then pass them into generateText or streamText. The SDK handles the execution automatically.

Yes. When your agent calls the MCP Server, the resulting JSON streams directly to your React or Next.js frontend. Users see the schedule build live.

You pass your endpoint token into the createMCPClient transport configuration. The Vinkius V8 Isolate Sandbox handles the actual service authentication behind the scenes.

You trigger the list_calendars tool through your agent prompt. The SDK executes the call and returns the active calendar IDs to your application state.

Vinkius processes your Apptoto contacts and appointment notes in an ephemeral sandbox. The container destroys itself after the request finishes, leaving zero traces of your clients' phone numbers or booking histories.
