How to Use the GetBlock (Web3 RPC Provider) MCP in Vercel AI SDK

Q: How do I connect Vercel AI SDK to GetBlock (Web3 RPC Provider)?

Install @ai-sdk/mcp and call createMCPClient. Pass your GetBlock endpoint URL to the HTTP transport.

Q: Can GetBlock (Web3 RPC Provider) estimate gas fees through Vercel AI SDK?

Yes. The ethestimategas tool calculates the exact compute cost for any transaction. Your agent can display this fee in the UI before prompting the user to sign.

Q: Does this MCP Server support custom smart contract reads?

You can query any contract using ethcall. Pass the target address and encoded data payload. The model will parse the hex response into readable text for your frontend.

Q: How do I handle multi-chain queries with GetBlock (Web3 RPC Provider) and Vercel AI SDK?

Load the entire MCP toolset into your streamText call. If a user asks for both Bitcoin and Ethereum stats, the agent fires btcgetblockcount and ethblocknumber concurrently.

Build live Web3 dashboards. Stream real-time blockchain data from GetBlock directly into your React app using Vercel AI SDK.

Perplexity

Stream Chain Data via Vercel AI SDK

The `eth_get_balance` and `sol_get_balance` tools fetch live wallet data straight from the network. Your Vercel AI SDK setup streams these integers directly to your frontend components. Users watch their portfolio load instantly without waiting for a backend polling loop to finish. You pass the tools into `streamText` and let the language model handle the formatting. If a user asks for their SPL token status, the agent hits `sol_get_token_account_balance` and pushes the UI update over the wire. Zero lag.

Execute Raw Transactions

The `btc_sendrawtransaction` tool broadcasts signed hex payloads to the Bitcoin network. You wire this up to a custom React confirmation button. The moment the user clicks approve, the payload fires and returns a transaction hash. Need smart contract interactions? The `eth_call` tool simulates execution before you commit to gas fees. Your interface updates with the exact contract response in milliseconds, giving users confidence before they sign.

Deep Transaction Tracing

The `debug_trace_transaction` tool pulls every internal state change from a specific hash. When a swap fails, your AI client reads the exact opcode where the revert happened. You render this trace data into a clean timeline component using `generateText`. Instead of dumping raw JSON-RPC logs on your users, the agent translates `debug_trace_call` outputs into plain English error messages.

Setup guide

Set up GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) 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 GetBlock (Web3 RPC Provider) transactions",
});

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