How to Use the TzKT (Tezos Indexer & Explorer API) MCP in Vercel AI SDK

Q: How does TzKT (Tezos Indexer & Explorer API) work with Vercel AI SDK?

The MCP Server exposes tools like listtransactions to your Vercel AI SDK client. When the user prompts for data, the results stream back into your React or Next.js component in real time.

Q: Can I track token transfers using TzKT (Tezos Indexer & Explorer API) and Vercel AI SDK?

Yeah, absolutely. You can call listtokentransfers to see every movement of FA1.2 or FA2 tokens between accounts. This data streams live into your UI, making it easy for users to audit asset flows.

Q: Does Vercel AI SDK support filtering for list accounts?

Yes. You can use listaccounts and filter the results by balance or activity type directly through your client calls.

Q: How do I get network statistics with TzKT (Tezos Indexer & Explorer API) using Vercel AI SDK?

You use the getstatistics tool. This pulls current network-wide metrics like Transactions Per Second (TPS) and total volume, which you can then display immediately in your application.

Streaming Blockchain Reads for Vercel AI SDK

When you call `list_transactions`, the results appear instantly, letting users track real-time activity without a loading spinner. This lets your frontend display block details using `get_block` or check account status via `get_account`. The data streams directly into the user interface.

MCP Server for Real-Time Account Status

Need to show a user's current holdings? You can use `list_token_balances` or check historical changes with `get_account_balance_history`. This allows you to build a component that updates account data as it arrives, showing everything from simple calls like `get_head` to complex reports using `get_contract_report`. It's perfect for building user-facing product dashboards where the client needs instant feedback on Tezos assets.

Monitoring Smart Contract Operations

Don't just check an account balance; track what happened. Use `get_operations_by_hash` to pull all transactions linked to a specific hash, or use `list_originations` to see how contracts got started. This gives your application the granular detail needed for debugging or deep dives into smart contract logic using `get_contract_code`.

Setup guide

Set up TzKT (Tezos Indexer & Explorer 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 TzKT (Tezos Indexer & Explorer 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 TzKT (Tezos Indexer & Explorer API) transactions",
});

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