How to Use the Memberstack MCP in Vercel AI SDK

Q: How do I hook up Memberstack to my Vercel AI SDK project?

Install @ai-sdk/mcp and initialize the client using the Vinkius HTTP transport URL. Once configured, pass the tool definitions directly into streamText or generateText so your agent can execute calls like getmember on demand.

Q: Can the Vercel AI SDK stream Memberstack plan changes?

Yes, it can. When the model calls listplans, the response streams directly into your UI components using the SDK's helper hooks. This prevents rendering delays and keeps your membership catalog up to date.

Q: How do I handle coupon codes in the chat interface?

Your agent uses listcoupons to retrieve active discounts. The SDK then streams these codes directly to the chat component, allowing users to apply them at checkout.

Stream Memberstack subscription data directly into your Vercel AI SDK frontend without laggy loading spinners.

Perplexity

Live member profile rendering via Vercel AI SDK

By combining this MCP Server with the Vercel AI SDK, your agent queries the Memberstack database using `get_member` and streams the JSON payload directly into your React component. The Vercel AI SDK handles the incoming stream on the edge, rendering the UI instantly as the Memberstack profile details resolve. You can also pull custom metadata on the fly. The Vercel AI SDK invokes `list_custom_fields` to map out form layouts, rendering custom Memberstack signup inputs on your Next.js frontend before the model even finishes generating the rest of the text.

Instant pricing updates in Vercel AI SDK chat

This MCP Server lets your conversational Vercel AI SDK interface dynamically list subscription pricing by invoking `list_plans` and `get_plan` inside your edge functions. The AI client formats the Memberstack plan details into clean, interactive UI cards that stream directly onto the user's screen. If a user asks for a discount, the Vercel AI SDK quickly checks `list_coupons` or `list_promotions` to present active Memberstack deals. The SDK handles this token-by-token, rendering the discount code immediately in the chat bubble without blocking the thread.

Live member search in your admin dashboard

When your support team searches for a user, the Vercel AI SDK uses `search_members` to look up accounts by email. The SDK streams the resulting list of matching Memberstack profiles into a dashboard table in real-time. You don't have to write custom API routes for every search variant. The Vercel AI SDK uses `list_members` to fetch the broader Memberstack list, then filters and structures the database payloads on the edge to match your dashboard's exact layout.

Setup guide

Set up Memberstack 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 Memberstack 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 Memberstack transactions",
});

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

Common questions about Memberstack MCP in Vercel AI SDK

Install `@ai-sdk/mcp` and initialize the client using the Vinkius HTTP transport URL. Once configured, pass the tool definitions directly into `streamText` or `generateText` so your agent can execute calls like `get_member` on demand.

Yes, it can. When the model calls `list_plans`, the response streams directly into your UI components using the SDK's helper hooks. This prevents rendering delays and keeps your membership catalog up to date.

It does. Because Vinkius hosts the server, your Vercel AI SDK code running on Edge Functions only makes a lightweight HTTP call, avoiding heavy Node.js dependencies.

Your agent uses `list_coupons` to retrieve active discounts. The SDK then streams these codes directly to the chat component, allowing users to apply them at checkout.

Your sensitive member profiles, custom fields, and plan configurations never touch third-party storage. Vinkius runs the server in an isolated sandbox, routing API requests directly between your AI client and Memberstack over encrypted channels.
