How to Use the Vast.ai (GPU Rental Cloud API) MCP in OpenAI Agents SDK

Q: How does the OpenAI Agents SDK handle GPU resource discovery?

It uses the searchoffers tool to query Vast.ai directly. You define what you need—say, an RTX 4090—and your AI client gets a list of matching market offers.

Q: What happens if I run out of budget while using Vast.ai (GPU Rental Cloud API) with the OpenAI Agents SDK?

The agent will fail cleanly when it tries to call rentinstance without sufficient funds, thanks to built-in guardrails. It won't attempt a partial deployment or leave you hanging.

Q: Does the MCP Server handle instance cleanup for me?

Yes, your agent uses deleteinstance to terminate resources immediately. This is crucial for managing costs when running multi-stage jobs on Vast.ai (GPU Rental Cloud API).

Q: How do I check the status of my deployed GPUs?

You call the listinstances tool. It gives you a complete inventory, letting you see which instances are running and where they're hosted.

Search available GPUs with the MCP Server

The `search_offers` tool lets your agent check what’s available on Vast.ai. You pass a JSON query, like looking for a specific GPU model, and get back current market listings. This is key when designing complex workflows; you don't want the agent trying to deploy hardware that doesn't exist or isn't priced right.

Rent new resources using OpenAI Agents SDK

Need compute power? The `rent_instance` tool handles deploying a GPU instance. Your agent submits the request, and you get back details on your newly provisioned resource. This allows specialized agents to act autonomously, requesting exactly the hardware they need for their current task without human intervention.

Manage cloud fleet with MCP Server

The `list_instances` tool gives a full rundown of all your rented resources. It's how you check on the status and details of every GPU instance deployed to Vast.ai. Furthermore, if an agent finishes its job or hits an error, it can use `delete_instance` immediately. This ensures you don't get charged for idle hardware.

Setup guide

Set up Vast.ai (GPU Rental Cloud API) 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 Vast.ai (GPU Rental Cloud API) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Vast.ai (GPU Rental Cloud API) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

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

asyncio.run(main())
