How to Use the Helius (Solana) MCP in OpenAI Agents SDK

Q: How do I connect Helius (Solana) to the OpenAI Agents SDK?

Use MCPServerStreamableHttp with your Vinkius endpoint URL. Pass the server instance into your Agent constructor via the mcpservers array. Set cacheToolsList=True to speed up initialization.

Q: Can OpenAI Agents SDK track NFTs using Helius (Solana)?

Yes, the server exposes getassetsbyowner and getassetbatch. Your agent can fetch compressed NFT data and even retrieve the Merkle proof via getassetproof for verification.

Q: Does Helius (Solana) support custom token routing in OpenAI Agents SDK?

You can query gettokenaccounts to find all accounts associated with a specific mint or owner. The agent can then use that data to construct valid transaction instructions before estimating fees.

Build production-grade Solana agents with OpenAI Agents SDK. Read chain data and route transactions through built-in safety guardrails.

Parse Solana state with OpenAI Agents SDK

The `parse_transactions` tool takes raw Solana transaction data and turns it into human-readable logs. Your agent doesn't have to guess what happened in a DeFi swap. It reads the exact token movements directly from the chain. You configure this MCP Server using `MCPServerStreamableHttp` in your async context manager. Pass it to the Agent constructor, and the model auto-discovers endpoints like `get_transaction_history` to pull enhanced logs without manual prompt engineering.

Track wallet balances and history

The `get_wallet_balances` endpoint fetches token and NFT holdings alongside their current USD values. Your agent gets a complete snapshot of a user's portfolio in a single call. No need to index the chain yourself. Combining this with `get_wallet_transfers` lets your system map incoming and outgoing flows. If you are building an automated trading assistant, the agent can verify funding sources using `get_wallet_funded_by` before executing any logic.

Estimate priority fees accurately

Helius exposes `get_priority_fee_estimate` to calculate exactly what a transaction needs to land on-chain. You pass the serialized transaction, and the tool returns the recommended micro-lamport bid. Relying on local node estimates often leads to dropped transactions during network spikes. This MCP endpoint pulls from real-time mempool data, ensuring your automated execution agents don't stall when Solana gets congested.

Setup guide

Set up Helius (Solana) 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 Helius (Solana) tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Raw RPC requires extensive boilerplate to parse account data. This server provides pre-indexed tools like `search_assets` and `get_wallet_identity` to resolve .sol domains instantly.

The server processes public wallet addresses and transaction hashes. Vinkius runs the connection in an ephemeral V8 Isolate Sandbox, meaning your queries vanish the moment the HTTP request completes. No logs remain on the infrastructure.
