How to Use the Keycloak MCP in Vercel AI SDK

Q: How do I stream Keycloak user directories to React with Vercel AI SDK?

Use createMCPClient to connect to the MCP Server over HTTP. Pass the tools from mcpClient.tools() into streamText and let your agent run listusers to render active accounts on the fly.

Q: How do I handle Keycloak client secret rotation securely in Vercel AI SDK?

Have your agent call regenerateclientsecret and pipe the output to your UI. Always call mcpClient.close() to clean up connections and prevent memory leaks in your Vercel serverless environment.

Q: Does Vercel AI SDK support custom UI components for Keycloak role mapping?

Yes, your Vercel AI SDK agent can call listroles and map them to your custom React components, updating the UI state as the Keycloak backend changes are completed.

Build live-updating Next.js security dashboards where your Vercel AI SDK agent updates Keycloak access controls on the fly.

Perplexity

Stream active user lists straight to your Next.js UI

Stop making users stare at loading spinners while your Next.js app fetches Keycloak identity profiles. This MCP Server lets your Vercel AI SDK agent call `list_users` and stream the results directly into your React components as they arrive. Your Next.js frontend renders the Keycloak user list in real-time. If you need to modify permissions, the Vercel AI SDK agent triggers `update_user` on the same screen, feeding Keycloak updates straight to your React UI.

Instant client secret rotation in edge functions

Handling client secrets at the edge usually means pain. Your Vercel AI SDK code can use this MCP Server inside lightweight Edge Functions to rotate credentials without cold-start delays. The agent reads the fresh payload from `get_client_secret` and updates your UI instantly. No heavy server-side frameworks required, just clean TypeScript streaming directly to your security admin console.

Real-time authentication flow visualization

Let your security admins design Next.js login steps using plain English. The Vercel AI SDK agent interprets their request, calls `create_auth_flow` to build the structure in Keycloak, and displays the configuration steps live. By combining `list_auth_flows` with Next.js UI streaming, your team watches the Vercel AI SDK agent construct complex multi-factor steps using this MCP Server. They can immediately see if a Keycloak step is misconfigured before deploying the Next.js app to production.

Setup guide

Set up Keycloak 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 Keycloak 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 Keycloak transactions",
});

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