How to Use the Arbiscan (Arbitrum Explorer) MCP in Mastra AI

Q: How do I set up human-in-the-loop approvals for this MCP Server?

Use Mastra's tool approval setting on the verifysourcecode tool. This pauses the workflow and alerts you before submitting any code to the network.

Q: How do I verify contracts with Arbiscan (Arbitrum Explorer) and Mastra AI?

Your agent can execute the verification workflow using the verifysourcecode tool. Mastra handles the multi-step polling process until the contract is verified.

Perplexity

Automate Arbitrum block monitoring with Mastra AI

The `get_block_countdown` and `get_block_reward` tools allow you to build automated workflows that trigger actions based on specific block heights. Mastra AI manages these triggers natively, executing your custom logic whenever a target block is reached. If the network congests or an API call drops, Mastra's built-in exponential backoff handles the retry logic automatically. Your monitoring agents stay online without manual intervention.

Build self-healing transaction tracking pipelines

The `get_tx_receipt_status` and `get_status` tools provide the raw execution data your workflows need to verify transaction success. If a critical transaction fails, your agent can branch conditionally to alert your team or retry with a higher gas limit. This gives you a resilient way to handle smart contract interactions. You write the logic once, and Mastra ensures your agent handles network hiccups gracefully.

Audit contract code via this MCP Server

The `get_source_code` and `verify_source_code` tools let your agents inspect contracts via this MCP Server before executing transactions. Mastra's workflow engine can pause execution for human approval if a contract looks suspicious. This adds a critical layer of safety to your automated operations. Your agent verifies the code on Arbiscan before interacting with any unverified address.

Setup guide

Set up Arbiscan (Arbitrum Explorer) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Arbiscan (Arbitrum Explorer) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "arbiscan-arbitrum-explorer-mcp-client",
  servers: {
    "arbiscan-arbitrum-explorer-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Arbiscan (Arbitrum Explorer) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Arbiscan (Arbitrum Explorer) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Arbiscan (Arbitrum Explorer) transactions"
);
console.log(result.text);
