How to Use the Cronoscan (Cronos Block Explorer) MCP in Vercel AI SDK

Q: How do I get started with Cronoscan (Cronos Block Explorer) and the Vercel AI SDK?

Install the @ai-sdk/mcp package from npm. Then, use createMCPClient with your Vinkius endpoint URL. You can pass the tools from mcpClient.tools() directly to the generateText or streamText functions.

Q: Can I show real-time ERC20 token transfers from Cronoscan (Cronos Block Explorer) in my Next.js app with the Vercel AI SDK?

Yes. The gettokentx and gettokennfttx tools are perfect for this. When you use them with streamText, the transfer events will render in your UI as they are found, not after a long wait.

Q: Does using Cronoscan (Cronos Block Explorer) with the Vercel AI SDK let me check the price of CRO?

It does. Your AI client can use the getethprice tool to fetch the latest CRO price. You can then stream this value directly into a React or Svelte component to display it to your users.

Stream Cronos blockchain data directly into your Next.js or React app with the Vercel AI SDK. No loading spinners, just live results.

Live CRO Balance & Tx History

This toolset lets you build UIs that show Cronos data in real time. Your users can check wallet balances or see transaction lists appear as the AI finds them. The AI SDK streams results from `get_balance`, `get_balance_multi`, and `get_tx_list` directly into your components. Forget waiting for a full API response. As the MCP Server processes data, your UI updates token by token, transaction by transaction. It's perfect for building dashboards or wallet frontends where users expect immediate feedback on their Cronos assets.

Inspect Contracts on the Fly

Let users pull smart contract details right inside your app. With a simple prompt, your AI can use the `get_abi` and `get_source_code` tools to display the inner workings of any verified contract on the Cronos chain. Your UI will render the code as it's streamed from the server. This isn't just for developers. You can build educational tools or verification flows where users confirm contract logic without leaving your site. The Vercel AI SDK makes it easy to present complex blockchain data in a clean, readable format.

Direct Node Access via this MCP Server

Run low-level Ethereum JSON-RPC calls through your AI client. The proxy tools (`proxy_eth_call`, `proxy_eth_get_block_by_number`) give you direct access to Cronos node functions without managing your own infrastructure. Your agent can estimate gas or check block details from a text prompt. Because you're using the Vercel AI SDK, even these technical results can be streamed into a UI. You could build a block explorer or a developer tool that shows node responses piece by piece, giving instant insight into the chain's state.

Setup guide

Set up Cronoscan (Cronos Block Explorer) 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 Cronoscan (Cronos Block Explorer) 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 Cronoscan (Cronos Block Explorer) transactions",
});

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

Common questions about Cronoscan (Cronos Block Explorer) MCP in Vercel AI SDK

Install the `@ai-sdk/mcp` package from npm. Then, use `createMCPClient` with your Vinkius endpoint URL. You can pass the tools from `mcpClient.tools()` directly to the `generateText` or `streamText` functions.

Yes. The `get_token_tx` and `get_token_nft_tx` tools are perfect for this. When you use them with `streamText`, the transfer events will render in your UI as they are found, not after a long wait.

You can build wallet dashboards that show live balances, transaction explorers, or tools that let users inspect smart contract ABIs. Because the AI SDK streams data, it's ideal for any user-facing application where responsiveness is key.

It does. Your AI client can use the `get_eth_price` tool to fetch the latest CRO price. You can then stream this value directly into a React or Svelte component to display it to your users.

Your requests, which may include Cronos wallet addresses, transaction hashes, or contract addresses, are sent to an isolated, ephemeral Vinkius sandbox. The MCP server processes the request, gets data from Cronoscan, and the entire environment is destroyed. Nothing is logged or stored.
