Live Web3 Data in Vercel AI SDK

Feed your UI live blockchain data using `ankr_getAccountBalance` or `eth_getBalance`. Your users watch data populate their dashboards while the agent processes the request. This MCP Server handles the RPC connection so your frontend stays responsive. It removes the need for manual polling or complex state management for wallet updates.

Real-time NFT and Token Tracking

Expose `ankr_getNFTsByOwner` or `ankr_getTokenPrice` to your AI client to build interactive asset viewers. The tools return raw data that you can map instantly to React components. Your application logic triggers these tools during the text generation stream. Users see the specific token prices or NFT holdings appear in their interface without waiting for a separate page reload.

Smart Contract Interaction

Execute `eth_call` or `eth_estimateGas` directly through your agent to prepare transactions for the end user. This allows your app to simulate outcomes before asking for a wallet signature. These operations function inside your Edge Functions. You gain high-performance access to chain state without managing your own infrastructure nodes.

Setup guide

Set up Ankr (Web3 Node 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 Ankr (Web3 Node 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 Ankr (Web3 Node API) transactions",
});

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