How to Use the Blastscan (Blast Network Explorer) MCP in OpenAI Agents SDK

Q: How do I set up Blastscan (Blast Network Explorer) with the OpenAI Agents SDK?

Install openai-agents and initialize the MCP server using MCPServerStreamableHttp with your Vinkius endpoint. Pass this server instance inside the mcpservers list when creating your Agent to give your OpenAI-powered agents access to the server.

Q: Can my OpenAI Agents SDK system handle gas estimation using Blastscan (Blast Network Explorer)?

Your agent runs proxyethestimategas to find out how much gas a transaction needs on Blast. This helps your specialized agents run cost checks before they execute on-chain actions.

Q: How do I cache the tool list to speed up my OpenAI agent?

Pass cacheToolsList=True when registering the Blastscan MCP server. This stops your agent from rebuilding the tool schema on every run, saving precious milliseconds.

Q: How does Blastscan (Blast Network Explorer) protect my wallet balances within OpenAI Agents SDK?

All requests for wallet balances via getetherbalance run through Vinkius's zero-trust sandboxed environment. Your private keys are never exposed because the server only reads public blockchain data.

Track Blast balances, transactions, and smart contracts directly from your OpenAI Agents SDK production workflows.

Track Blast transactions securely using OpenAI Agents SDK

The `get_normal_transactions` and `get_internal_transactions` tools feed direct on-chain activity into your OpenAI Agents SDK workflow. Your agent parses live Blast network histories while built-in safety guardrails prevent execution errors before they hit production. You configure the server as a streamable HTTP source inside an async context manager. This setup automatically routes discovered Blast transaction data to specialized sub-agents for deep analysis.

Verify smart contracts on Blast with agent guardrails

The `get_contract_abi` and `get_contract_source_code` tools give your OpenAI-powered agents direct access to verified source code on the Blast network. By putting these tools behind OpenAI's native validation layers, you ensure the agent never executes unverified bytecode. This setup lets you build a specialized auditor agent that pulls the ABI, checks functions, and hands off the data to a developer agent. Everything runs through your OpenAI dashboard, giving you a full trace of how the agent analyzed the contract.

Monitor ERC20 token metrics via MCP Server tools

This MCP Server exposes the `get_erc20_token_balance` and `get_erc20_token_supply` tools to track token distribution across Blast addresses. Your OpenAI agent queries balances and calculates market share without hardcoding API endpoints. Setting `cacheToolsList=True` during initialization keeps your agent fast by avoiding redundant schema lookups. You get real-time token metrics fed straight into your production agent's decision loop.

Setup guide

Set up Blastscan (Blast Network Explorer) MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Blastscan (Blast Network Explorer) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Blastscan (Blast Network Explorer) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Blastscan (Blast Network Explorer) tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Blastscan (Blast Network Explorer) Agent",
            instructions="You have access to Blastscan (Blast Network Explorer) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Blastscan (Blast Network Explorer) MCP in OpenAI Agents SDK

Install `openai-agents` and initialize the MCP server using `MCPServerStreamableHttp` with your Vinkius endpoint. Pass this server instance inside the `mcp_servers` list when creating your Agent to give your OpenAI-powered agents access to the server.

Your agent runs `proxy_eth_estimategas` to find out how much gas a transaction needs on Blast. This helps your specialized agents run cost checks before they execute on-chain actions.

The Vinkius platform handles the underlying API limits, so your OpenAI Agents SDK setup only focuses on agent orchestration. You can safely run concurrent queries across tools like `get_logs` without your Python code crashing.

Pass `cacheToolsList=True` when registering the Blastscan MCP server. This stops your agent from rebuilding the tool schema on every run, saving precious milliseconds.

All requests for wallet balances via `get_ether_balance` run through Vinkius's zero-trust sandboxed environment. Your private keys are never exposed because the server only reads public blockchain data.
