How to Use the Infura (Ethereum Node RPC Provider) MCP in OpenAI Agents SDK

Q: How do I connect the Infura (Ethereum Node RPC Provider) to OpenAI Agents SDK?

Install openai-agents first. Pass the Vinkius HTTP endpoint into MCPServerStreamableHttp and assign it to the agent constructor. Your agent auto-discovers all 20 tools.

Q: Can my agent estimate gas using Infura (Ethereum Node RPC Provider) in OpenAI Agents SDK?

Yes, the agent calls ethestimateGas and getsuggestedgasfees to calculate transaction costs. This ensures your transactions do not get stuck in the mempool due to low gas.

Q: Does this MCP Server support real-time event filtering?

It includes ethnewFilter and ethgetFilterChanges for polling. Your agent can monitor smart contract events directly without writing custom WebSockets logic.

Q: How does OpenAI Agents SDK handle rate limits when calling Infura (Ethereum Node RPC Provider)?

Set cacheToolsList=True during initialization to avoid redundant schema requests. Vinkius handles the underlying connection pooling to prevent rate-limit exhaustion.

Read Live Blockchain State

This Infura MCP Server provides your agent with direct access to 20 low-latency JSON-RPC endpoints. Your Python code will spin up agents that instantly pull balances via `eth_getBalance` and verify smart contract bytecode using `eth_getCode`. Instead of coding custom API clients, you let the SDK auto-discover these blockchain tools. Your agent reads block details with `eth_getBlockByNumber` and tracks logs using `eth_getLogs` without writing a single line of integration glue.

Estimate Fees and Broadcast Transactions

The Infura MCP Server lets your OpenAI Agents SDK application estimate execution costs and submit transactions directly to the mempool. It uses `eth_estimateGas` to calculate execution limits before calling `get_suggested_gas_fees` for EIP-1559 pricing. Once your agent generates a payload, it broadcasts the signed payload using `eth_sendRawTransaction`. The agent then monitors execution status by querying `eth_getTransactionReceipt` until the transaction is mined.

Secure Multi-Agent Workflows with OpenAI Agents SDK

This Infura MCP Server integrates into multi-agent systems to separate read operations from transaction execution. You can route public chain checks like `eth_chainId` and `eth_blockNumber` to a read-only agent. A separate, highly guarded agent handles `eth_sendRawTransaction`. This setup prevents unauthorized trades while maintaining high performance across your entire agent team.

Setup guide

Set up Infura (Ethereum Node RPC Provider) 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 Infura (Ethereum Node RPC Provider) tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
