How to Use the Blockchain.com Data MCP in OpenAI Agents SDK

Q: How do I configure Blockchain.com Data inside the OpenAI Agents SDK?

Install the SDK first. Register the MCP server using MCPServerStreamableHttp with your Vinkius endpoint, then pass it directly into your Agent constructor. Turn on cacheToolsList to speed up tool discovery.

Validate Bitcoin Address Balances in OpenAI Agents SDK

Stop guessing if a wallet has funds before triggering a payout. Hook up `get_address` to your OpenAI agents to check actual ledger states on the fly. This MCP Server lets your agent inspect balances and transaction histories without hardcoding API keys. The SDK handles validation before your agent acts. If the agent tries to parse a malformed Bitcoin address, your guardrails catch it before hitting the network. You get clean, verifiable ledger data directly in your OpenAI run logs.

Track Live Mempool Friction

Congested blocks stall business transactions. Your agents can monitor network health using `get_mempool_stats` and `list_unconfirmed_transactions` to adjust fee strategies dynamically. If fees spike, the agent hands off the task to a specialized gas-optimization agent. Using this MCP setup, your system holds off on broadcasting expensive transactions until mempool congestion clears.

Real-Time Price Checks and Network Stats

Feed current market values into your trading logic instantly. Let your agent run `get_ticker` to pull exact BTC conversion rates across different fiat currencies during execution. It combines these prices with general network health from `get_network_stats`. This gives your autonomous agents the raw context needed to make smart, real-time financial decisions.

Setup guide

Set up Blockchain.com Data 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 Blockchain.com Data tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Blockchain.com Data MCP in OpenAI Agents SDK

Install the SDK first. Register the MCP server using `MCPServerStreamableHttp` with your Vinkius endpoint, then pass it directly into your `Agent` constructor. Turn on `cacheToolsList` to speed up tool discovery.

Yes, you control this through your agent's tool declaration list. Only pass the specific tools like `get_ticker` or `get_address` if you want to restrict the agent from reading block details.

Absolutely, you can set it up that way. Using this MCP integration, you can build a pipeline where one agent monitors network congestion using `get_mempool_stats` and hands off execution to a transaction-broadcasting agent once fees drop.

Vinkius manages the underlying connections to the Blockchain.com API. Your agents won't get blocked by sudden rate limits when pulling heavy block data.

Yes. Every query for a Bitcoin address or block hash goes through a secure V8 sandbox. No search data is stored or logged on the Vinkius platform after the request resolves.
