Real-time call data in Vercel AI SDK

Feed your UI live logs using the `list_calls` tool. Your application renders the data as it arrives, avoiding laggy loading states. This MCP Server pushes specific interaction timestamps directly to your React components. The result is a dashboard that feels responsive and alive.

Direct messaging via JustCall tools

Trigger the `send_message` tool to dispatch SMS alerts immediately upon user input. Your AI client handles the logic while you stay focused on the view layer. Connect your frontend forms to the backend logic without writing custom API wrappers. Every message sent is tracked through the standard output pipeline.

Contact management for AI-driven apps

Fetch customer profiles using `get_contact` to personalize responses in your chatbot. The data flows through the SDK's streaming transport directly into your generative flow. Updating your CRM records happens behind the scenes with `create_contact`. You maintain a clean database without leaving your development environment.

Setup guide

Set up JustCall 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 JustCall 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 JustCall transactions",
});

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

Common questions about JustCall MCP in Vercel AI SDK

Install the MCP client package and configure the HTTP transport URL. Pass the tools returned by the server into your generateText call to start executing commands.

Yes. Since this server exposes tools that the SDK consumes, your AI client can stream the results of `list_calls` or `list_messages` directly into your UI components.

Absolutely. By hooking `send_message` to your AI logic, you can trigger automated responses based on incoming chat context or user data.

It is. The lightweight transport layer works perfectly within the constraints of Vercel Edge Runtime environments.

Your API credentials stay local to your environment. The MCP Server acts as a proxy, ensuring that sensitive call logs and customer data are never exposed in transit.
