How to Use the Vast.ai (GPU Rental Cloud API) MCP in LlamaIndex

Q: How do I build an RAG system using Vast.ai (GPU Rental Cloud API) and LlamaIndex?

First, you run searchoffers to get current market data. Then, pass that structured result into the indexer. The resulting vector store allows you to query this live GPU pricing information later.

Q: What kind of deployments can LlamaIndex track using Vast.ai (GPU Rental Cloud API)?

You can index the outcomes of rentinstance and deleteinstance. This means your knowledge base tracks not just what was rented, but the full lifecycle—when it started and when it was terminated.

Q: Can LlamaIndex query past GPU configurations with Vast.ai (GPU Rental Cloud API)?

Yes. By indexing historical listinstances outputs, you can ask semantic questions like, 'Show me all instances that ran over 32GB of VRAM,' and get accurate answers.

Turn GPU rental data into searchable knowledge bases with LlamaIndex.

Creating Knowledge from MCP Server

LlamaIndex indexes the output of tools like `list_instances` so you can query historical resource configurations. Instead of just seeing a list, you're asking: 'What were our biggest GPU deployments last month?' and getting answers grounded in that API data.

RAG Applications with LlamaIndex

You can combine unstructured documents with live API data. For instance, if a user asks about the cost of an 'RTX 4090', LlamaIndex combines that search result from `search_offers` with your internal policy manual to give a fully contextual answer.

Managing Deployments via MCP Server

When using `rent_instance`, the resulting instance ID and deployment details become indexable knowledge. You can query past sessions to know exactly which GPU setup worked best for a specific deep learning model, eliminating guesswork.

Setup guide

Set up Vast.ai (GPU Rental Cloud API) MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Vast.ai (GPU Rental Cloud API) MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Vast.ai (GPU Rental Cloud API) tools.",
)
response = await agent.run("List recent Vast.ai (GPU Rental Cloud API) data")

Yes. By indexing historical `list_instances` outputs, you can ask semantic questions like, 'Show me all instances that ran over 32GB of VRAM,' and get accurate answers.

The server provides four key tools covering the entire GPU lifecycle: search, rent, list, and delete. This gives LlamaIndex plenty of structured data to build a rich knowledge graph.

The server touches instance metadata and search offers results. We recommend indexing only anonymized resource identifiers, keeping sensitive pricing or user details out of the vector store.
