Real-time user provisioning in Vercel AI SDK

Trigger account creation and group assignments instantly from your UI. By mapping `create_user` and `add_group_member` to your streamText output, you push identity changes to the server without forcing a page reload. Your users see their profile updates reflected as the AI streams the response. This creates a live feedback loop that feels native to your React or Next.js application.

Dynamic authentication state management

Handle complex login flows using `login` and `issue_jwt` directly within your edge functions. The MCP server ensures your auth logic stays isolated from your core UI code while maintaining type safety. Managing sessions becomes a background task for your agent. You verify status with `get_system_status` to ensure the identity provider is reachable before showing restricted content.

Automated MFA and security enforcement

Secure user actions by invoking `enable_mfa` and `generate_mfa_secret` inside your request handlers. You control exactly when to challenge a user for a secondary token based on the sensitivity of the operation. Your application logic remains clean because the heavy lifting happens server-side. You simply define the trigger point and let the tool handle the cryptographic handshake.

Setup guide

Set up FusionAuth (Enterprise Identity & Auth) 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 FusionAuth (Enterprise Identity & Auth) 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 FusionAuth (Enterprise Identity & Auth) transactions",
});

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

Common questions about FusionAuth (Enterprise Identity & Auth) MCP in Vercel AI SDK

You should use the authProvider setting within your client configuration. This ensures every request from the Vercel AI SDK carries the necessary credentials to authorize identity operations.

Yes, the server is built for high-performance environments. You can execute these tools in Edge Functions, provided your network allows outbound traffic to the host.

Yes, you can intercept tool calls before execution. This allows you to prompt the user for confirmation before sensitive actions like deleting a tenant or user.

The SDK catches the error and allows you to handle it gracefully in your UI. You can display a custom error component while the agent retries the operation.

Data is transmitted over encrypted channels only. The server interacts with your user records directly, and no PII is cached by the MCP bridge itself.
