How to Use the Deck of Cards MCP in Vercel AI SDK

Q: How does Deck of Cards handle real-time streaming in Vercel AI SDK?

The SDK reads the tool outputs like drawcards and streams the JSON chunks directly to your React components. This lets you render card faces as they are drawn instead of waiting for the entire API response to complete.

Q: How do I manage multiple player hands using Deck of Cards and Vercel AI SDK?

You use addtopile to define separate piles for each player's hand. The SDK tracks these pile states and streams the updates, so each player's interface updates independently as cards move.

Q: What happens if a card draw fails during a Vercel AI SDK stream?

If drawcards fails because the deck is empty, the server returns an error. The SDK catches this in the stream, allowing your UI to instantly prompt the user to trigger reshuffledeck.

Real-time card dealing for React interfaces

The `draw_cards` tool pulls cards from a virtual deck and flings them straight into your Vercel AI SDK stream. Your users see cards hit their hand in real-time. No loading spinners. No waiting around. If you need a clean slate, the agent triggers `create_new_deck` and shuffles it instantly. The fresh layout renders immediately as the JSON streams into your UI, keeping the game snappy.

Build custom card piles inside Edge Functions

The `add_to_pile` tool lets your Vercel AI SDK agent group cards into custom hands or discard piles on the fly. Since this MCP Server runs in a zero-trust sandbox, you can run these card operations inside lightweight edge runtimes without hitting nasty cold starts. When players want to pull from specific spots, the agent calls `draw_from_pile_bottom` or `draw_from_pile_random` to fetch the exact cards. The SDK handles the state updates on the edge, keeping the game state perfectly synchronized with your React frontend.

Instant deck resets using Vercel AI SDK

The `return_pile_to_deck` tool returns all piled cards back to the main deck instantly when a round ends. This action is processed by the MCP Server and immediately reflected in the stream, so the UI resets without a full page reload. To prepare the next round, the agent runs `shuffle_new_deck` to randomize the deck. Your frontend receives the fresh deck structure via the SDK stream, allowing you to animate the shuffle transition immediately.

Setup guide

Set up Deck of Cards 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 Deck of Cards 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 Deck of Cards transactions",
});

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

Common questions about Deck of Cards MCP in Vercel AI SDK

The SDK reads the tool outputs like `draw_cards` and streams the JSON chunks directly to your React components. This lets you render card faces as they are drawn instead of waiting for the entire API response to complete.

Yes. You connect the SDK to the Vinkius host using the HTTP transport. This setup works perfectly in Edge environments since it relies on lightweight fetch requests to manage your deck state.

You use `add_to_pile` to define separate piles for each player's hand. The SDK tracks these pile states and streams the updates, so each player's interface updates independently as cards move.

If `draw_cards` fails because the deck is empty, the server returns an error. The SDK catches this in the stream, allowing your UI to instantly prompt the user to trigger `reshuffle_deck`.

No, this MCP Server only processes temporary deck IDs, card codes, and pile names. All operations run in an ephemeral sandbox, meaning no private player details or persistent game histories are stored on the server.
