How to Use the Arweave MCP in Vercel AI SDK

Q: How do I query Arweave data in Vercel AI SDK?

You initialize the client with createMCPClient and pass the tools into your streamText configuration. It connects your frontend directly to the network nodes.

Q: Can Vercel AI SDK handle large Arweave data sets?

Yes, but keep your queries focused. Use querygraphql to fetch only the specific transaction metadata you need rather than pulling raw blocks.

Stream permanent storage data directly into your Vercel AI SDK interface without waiting for clunky background processes.

Perplexity

Real-time Arweave data streaming

Feed blockchain state directly into your React components. Use `get_network_info` to show network health or `get_wallet_balance` to display live holdings as the AI processes user requests. Your UI updates instantly as the MCP Server pushes data through the SDK. Stop hiding behind loading spinners and show your users the permaweb state as it happens.

Instant transaction verification

Verify chain state mid-stream using `get_transaction_status`. You can confirm if a file hit the permaweb before the agent finishes its response. This keeps your application state in sync with the network. No more guessing if a submission succeeded or stalled.

Precise storage cost estimation

Calculate upload fees before the user commits data. Call `get_storage_price` to fetch the current Winstons cost and display it in your component. This lets you build transparent billing flows. Users know exactly what they pay to store files permanently before the `submit_transaction` call fires.

Setup guide

Set up Arweave 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 Arweave 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 Arweave transactions",
});

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

Common questions about Arweave MCP in Vercel AI SDK

You initialize the client with `createMCPClient` and pass the tools into your `streamText` configuration. It connects your frontend directly to the network nodes.

Yes, but keep your queries focused. Use `query_graphql` to fetch only the specific transaction metadata you need rather than pulling raw blocks.

Not if you use the MCP Server correctly. Offload heavy data inspection to the server and only stream the final results to your UI components.

Data lives on the decentralized permaweb. The MCP Server acts as the bridge that lets your application interact with these immutable blocks.

The server doesn't store your keys. It handles the transaction handshake, but you should always manage your signing logic inside a secure environment.
