How to Use the Kinde (Modern Authentication) MCP in Vercel AI SDK

Q: How do I use Kinde (Modern Authentication) with the Vercel AI SDK?

You connect this MCP server's URL to the createMCPClient function in your Vercel AI SDK app. Then you pass the tools from mcpClient.tools() into your generateText or streamText call. Your agent can then use the Kinde tools.

Q: Can I update user roles in Kinde from my app?

Yes. Your AI agent can use the updateuser tool. You'll need to provide the user's ID and the new role information in the data payload for the tool call.

Stream Kinde user data directly into your Vercel AI SDK components, showing live results to your users.

Perplexity

Create Users and Orgs On The Fly

This server gives your AI client tools to create new Kinde users and organizations. With the Vercel AI SDK, you can build a UI where a support person types in a new user's details, hits enter, and the AI agent calls `create_user` in the background. Because the SDK streams results, you don't need a loading spinner. The new user or organization appears in your UI the instant the tool call finishes. It's a much better experience for anyone using your app.

Build Live Admin Dashboards

Use the `list_users` and `list_organizations` tools to populate your admin panels. Your agent can fetch a complete list of users and stream the data directly into a React or Svelte component. It's a simple way to build a real-time view of your Kinde instance. Forget about wiring up your own API endpoints and data-fetching hooks. Just tell your agent to `list_users` and let the Vercel AI SDK handle the rest. You get a live, responsive dashboard with just a few lines of code.

Manage Roles with this MCP Server

Your agent can check what's possible before it acts. The `list_roles` and `list_permissions` tools let your agent see all available roles and permissions in Kinde. This is great for building UIs that let admins assign roles dynamically. Once the admin makes a choice, the agent uses `update_user` to apply the changes. The whole process feels fast and interactive because the Vercel AI SDK closes the loop between your UI and the MCP tools.

Setup guide

Set up Kinde (Modern Authentication) 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 Kinde (Modern Authentication) 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 Kinde (Modern Authentication) transactions",
});

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