How to Use the FtmScan (Fantom Network Explorer) MCP in OpenAI Agents SDK

Q: Can my agent check ERC20 token supplies using FtmScan (Fantom Network Explorer) in OpenAI Agents SDK?

Yes, your agent can run geterc20tokensupply to fetch the total supply of any contract. This works out of the box without manual ABI parsing.

Q: Can I monitor real-time gas prices with this setup?

You can use getftmlastprice to check the current market price of FTM. For block timings, getblockcountdown estimates the remaining time until a specific block is mined.

Build production-ready OpenAI Agents SDK systems that query Fantom blockchain data directly without hardcoding API endpoints.

Perplexity

Trace Fantom transaction flows instantly

`get_normal_transactions` pulls the full history of any Fantom address directly into your MCP Server runtime. The tool returns clean, structured transaction lists that your agent can parse to find recipient addresses, gas usage, or block timestamps. You don't have to write custom parser logic. The agent uses `get_internal_transactions` alongside normal history to map contract calls and trace where funds actually went. If a transaction failed, `get_transaction_status` checks the execution state so your agent can stop tracing dead ends immediately.

Verify contract code inside OpenAI Agents SDK

`get_contract_source_code` retrieves verified Solidity source files directly into the context window of your agent. This lets your system analyze smart contracts for vulnerabilities or verify deployment parameters on the fly. No manual copying from browser tabs. Your agent can also fetch raw ABIs using `get_contract_abi` to prepare transaction payloads or encode parameters. This raw data feeds directly into your execution pipeline, keeping your MCP agent's context clean and focused on verified on-chain code.

Track token balances across wallets

`get_ftm_balance` retrieves the native gas token balance for any single address on the Fantom network. If your agent needs to check multiple wallets in a single run, `get_ftm_balance_multi` batches the requests to keep your API consumption low and execution fast. For custom assets, `get_erc20_token_balance` checks specific token holdings, while `get_erc20_transfers` and `get_erc721_transfers` track the movement of fungible and non-fungible tokens. This gives your MCP client a complete view of any wallet's asset history.

Setup guide

Set up FtmScan (Fantom 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 FtmScan (Fantom Network Explorer) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives FtmScan (Fantom 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 FtmScan (Fantom 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="FtmScan (Fantom Network Explorer) Agent",
            instructions="You have access to FtmScan (Fantom Network Explorer) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about FtmScan (Fantom Network Explorer) MCP in OpenAI Agents SDK

Install the SDK with pip, then initialize the server using the `MCPServerStreamableHttp` class. Pass the server instance directly into your Agent constructor's `mcp_servers` list to auto-discover all 19 tools.

Yes, your agent can run `get_erc20_token_supply` to fetch the total supply of any contract. This works out of the box without manual ABI parsing.

The server runs in a dedicated sandbox on Vinkius, which manages connection pooling. You should configure caching on your agent to avoid hitting FtmScan rate limits during parallel runs.

You can use `get_ftm_last_price` to check the current market price of FTM. For block timings, `get_block_countdown` estimates the remaining time until a specific block is mined.

Vinkius runs the server in an ephemeral V8 sandbox, meaning your queried wallet addresses and transaction hashes never persist on disk. All requests go directly to FtmScan via HTTPS and vanish when the session closes.
