How to Use the CardanoScan (Cardano Block Explorer API) MCP in Vercel AI SDK

Q: How do I stream Cardano block data into a React component using CardanoScan (Cardano Block Explorer API) and the Vercel AI SDK?

Pass the tools from this MCP server to streamText. The AI SDK automatically handles streaming structured tool data, which you can then render piece by piece in your React UI for a live-updating display.

Q: Can I build a real-time Cardano wallet tracker with CardanoScan (Cardano Block Explorer API) and the Vercel AI SDK?

Yes. Use the listaddresstransactions tool. The Vercel AI SDK streams the results, so you can build a UI where transaction lists appear to load instantly, line by line.

Q: What's the best way to show Cardano stake pool stats with CardanoScan (Cardano Block Explorer API) and the Vercel AI SDK?

Combine the listpools and getpool tools. Your agent can fetch a list and then get details for a specific pool, streaming all the data directly into your frontend components for a responsive dashboard experience.

Stream Cardano chain data directly into your Next.js app with the Vercel AI SDK. No more loading spinners.

Query Live Transaction Data

This toolset connects your UI to the Cardano blockchain. You can pull transaction details with `get_transaction` or list all transactions for a wallet using `list_address_transactions`. Because you're using the Vercel AI SDK, this data streams directly into your React components. Your users see transaction histories populate in real-time, cell by cell, instead of waiting for a full API response to load.

Track Native Assets and Pools

Give your users a live look into Cardano's native assets and stake pools. Use `get_asset` to show token details or `get_pool` to display validator information. The `list_pools` tool is perfect for building a dashboard. Hook it up to the AI SDK and watch your UI build a dynamic, sortable list of stake pools as the data streams in from the MCP Server.

Inspect Blocks and Epochs via AI SDK

Go deeper into the blockchain's structure. Your agent can fetch specific block data with `get_block` or check the current network state with `get_latest_epoch`. This is great for building block explorer-style features. An end-user can ask your AI "show me the last 5 blocks," and your app, powered by the Vercel AI SDK, will stream the results from `get_latest_blocks` right onto their screen.

Setup guide

Set up CardanoScan (Cardano Block Explorer API) 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 CardanoScan (Cardano Block Explorer API) 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 CardanoScan (Cardano Block Explorer API) transactions",
});

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