Perplexity

Automate card lifecycle management

Stop manual procurement tasks by letting your agent handle card creation and status changes. When you need to spin up a new payment method, the agent calls `create_card` to generate a virtual card instantly. If you detect suspicious activity or a vendor goes rogue, the agent triggers `freeze_card` to kill the connection. This keeps your budget tight and prevents unauthorized charges from hitting your account.

Track SaaS spend with OpenAI Agents SDK

Your agent pulls real-time financial data to monitor your subscription footprint. By invoking `list_subscriptions` and `get_subscription`, the agent flags duplicate tools or underused software licenses. This visibility stops shadow IT before it starts. The agent reports back on exactly what you are spending, allowing you to reallocate funds to higher-priority projects without leaving your code.

Audit transactions with precision

Get deep insight into every dollar spent across your organization using the `list_transactions` tool. Your agent parses these logs to reconcile expenses against your internal budget requirements. Use `get_transaction` to investigate specific line items that look off. You get the raw data needed to keep your books clean, managed by an agent that never misses a detail.

Setup guide

Set up NachoNacho 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 NachoNacho tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
