How to Use the Blockscout MCP in Vercel AI SDK

Q: How do I connect Blockscout to my Vercel AI SDK project?

Install the @ai-sdk/mcp package and initialize the client with your Vinkius endpoint. You then pass the tools directly into streamText to let your agent call them.

Q: Does the Blockscout and Vercel AI SDK setup support custom RPC calls?

Yes, you can use the jsonrpc tool to execute any standard Ethereum JSON-RPC 2.0 method. This lets your frontend request custom blockchain state updates dynamically.

Q: Can I query native coin supplies?

The gettotalsupply tool returns the exact circulating supply of the native network coin. This keeps your UI metrics accurate without relying on third-party pricing APIs.

Feed live Ethereum blockchain data directly into your React components using the Vercel AI SDK.

Render live token balances in your UI

The `list_token_balances` tool fetches ERC-20 token balances for any wallet address on the network. Your UI components render these assets as they stream in, bypassing the usual loading spinners that kill user engagement.

Audit smart contracts directly inside your chat

The `get_contract_source_code` tool pulls verified Solidity code directly from the explorer. Your agent reads this source code to explain complex logic or spot vulnerabilities right inside the chat window.

Fetch on-chain histories using the Blockscout MCP Server

The `get_account_transactions` tool extracts the full transaction history for any target wallet. Combine this with `get_account_internal_transactions` to trace complex smart contract calls.

Setup guide

Set up Blockscout 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 Blockscout 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 Blockscout transactions",
});

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

Common questions about Blockscout MCP in Vercel AI SDK

Install the `@ai-sdk/mcp` package and initialize the client with your Vinkius endpoint. You then pass the tools directly into streamText to let your agent call them.

Yes, this integration runs perfectly on edge runtimes. The agent uses get_contract_source_code to pull Solidity files and streams the explanation to the client instantly.

Yes, you can use the json_rpc tool to execute any standard Ethereum JSON-RPC 2.0 method. This lets your frontend request custom blockchain state updates dynamically.

The get_total_supply tool returns the exact circulating supply of the native network coin. This keeps your UI metrics accurate without relying on third-party pricing APIs.

Vinkius runs this MCP Server in an isolated sandboxed environment, meaning your queries never leak. Only the specific Ethereum addresses, transaction hashes, and smart contract ABIs you explicitly request are processed, and they are never stored or used for training.
