How to Use the Blockscout MCP in OpenAI Agents SDK

Q: Can I use Blockscout with OpenAI Agents SDK for real-time monitoring?

Yes, you can trigger getindexingstatus to confirm the chain data is current. This ensures your agent isn't acting on delayed information.

Query Ethereum data directly in your OpenAI Agents SDK production pipeline without leaving your Python environment.

Fetch blockchain state for OpenAI Agents SDK

Call `get_account_balance` or `get_account_transactions` to pull live data into your agent's reasoning loop. This setup lets your system check wallet activity without manual API polling. Your agent uses these tools to verify account history before making decisions. It keeps your logic tethered to the actual chain state rather than stale logs.

Inspect smart contracts with OpenAI Agents SDK

Use `get_contract_source_code` to pull raw Solidity directly into your context window. Your agent can read the code to identify vulnerabilities or check function logic on the fly. This MCP server handles the formatting, so your model receives clean, readable text. It removes the need for manual file uploads or brittle scraping scripts.

Execute custom calls for OpenAI Agents SDK

Run raw commands through `json_rpc` to bypass standard tool limitations. This gives your agent full access to custom blockchain queries that aren't covered by basic endpoints. You retain control over the request structure, ensuring your agent only sends valid hex data. It's the most flexible way to interact with nodes during a production run.

Setup guide

Set up Blockscout 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 Blockscout tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Blockscout 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="Blockscout Agent",
            instructions="You have access to Blockscout tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Blockscout MCP in OpenAI Agents SDK

Yes, you can trigger `get_indexing_status` to confirm the chain data is current. This ensures your agent isn't acting on delayed information.

The server translates raw blockchain responses into structured JSON that your agents parse natively. You won't need custom adapters to handle the payload.

Absolutely. Since the tools are discovered dynamically, you can apply your standard validation logic to every output before the agent proceeds.

Vinkius handles the auth layer, so your tokens never touch your local code. You only pass the endpoint URL to your agent configuration.

This server only reads public on-chain data like transaction hashes and wallet balances. It never stores your private keys or sensitive user metadata.
