How to Use the NMKR Cardano MCP in OpenAI Agents SDK

Q: How do I connect NMKR Cardano to the OpenAI Agents SDK?

Install openai-agents and define the MCP Server using MCPServerStreamableHttp. Pass the Vinkius endpoint URL in the parameters. Then include it in the mcpservers list when initializing your Agent.

Q: Can the OpenAI Agents SDK cache NMKR Cardano API responses?

Yes. Set cacheToolsList=True when configuring the server. This prevents the agent from re-fetching the available tool definitions from NMKR on every single execution loop.

Q: Which NMKR Cardano tools should my OpenAI Agents SDK pipeline prioritize?

Start with validatenftmetadata and getmintcouponbalance. These two tools prevent failed transactions and ensure you have enough credits before your agent attempts any high-volume operations.

Q: Does this setup handle sub-customer accounts?

You can track them. The listsubcustomers tool returns the accounts nested under your main NMKR profile. Your agent can iterate through these to generate unified reports.

Connect the NMKR Cardano MCP Server to your OpenAI Agents SDK to manage NFT project assets and payouts with built-in execution guardrails.

OpenAI Agents SDK Asset Tracking

Your production agent needs real-time visibility into your Cardano project state. Using `get_project_counts`, the system pulls asset metrics directly from NMKR Studio. If you need specific asset data, `list_project_nfts` and `get_nft_details` fetch the exact metadata for individual tokens. OpenAI's built-in tracing logs these fetch operations automatically. You see exactly what the agent pulled before it decides to act on the data. Before running a large batch, you can also check `get_project_discounts` to ensure your volume pricing applies correctly.

Pre-Mint Metadata Validation

Broken metadata ruins NFT drops. Instead of waiting for a failed on-chain transaction, your agent runs `validate_nft_metadata` to catch formatting errors early. This MCP Server tool checks the structure against CIP-25 standards before any ADA gets spent. You can configure OpenAI guardrails to require this validation step before proceeding. If the metadata fails the check, the agent halts the pipeline and alerts your team. It prevents malformed assets from ever reaching the minting phase.

Managing Payouts and Coupons

Running an NFT marketplace requires strict tracking of where the money goes. Your agent uses `list_payout_wallets` and `list_split_addresses` to verify the exact Cardano addresses configured for revenue sharing. It also tracks `list_vesting_addresses` for locked team allocations. Minting operations burn through platform credits. The agent calls `get_mint_coupon_balance` to check your available NMKR coupons. If the balance drops below your defined safety threshold, a specialized billing agent can take over the workflow to handle replenishment.

Setup guide

Set up NMKR Cardano 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 NMKR Cardano tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

The server only reads payout and split addresses via the NMKR API. Vinkius runs the connection inside an ephemeral V8 Isolate Sandbox. The process terminates immediately after fetching your wallet strings, leaving no residual memory of your financial routing.
