How to Use the CoreWeave (AI GPU Cloud) MCP in LlamaIndex

Q: How does LlamaIndex avoid hallucinating CoreWeave (AI GPU Cloud) cluster details?

By forcing the agent to fetch live data via getcluster before answering. This raw JSON payload is injected directly into the LLM context window, ensuring the response matches actual physical state.

Q: Can I build a semantic search tool for CoreWeave (AI GPU Cloud) logs in LlamaIndex?

Yes, you can use querylogs to ingest raw Loki logs, parse them into document chunks, and index them. This lets you run natural language queries to find specific error patterns across your GPU nodes.

Q: How do I filter which CoreWeave (AI GPU Cloud) tools are available to the LlamaIndex MCP Server?

Use the allowedtools filter during MCP client setup. This restricts the agent to read-only actions like listvpcs while blocking destructive tools like deletevpc.

Q: Does this setup support incremental indexing of infrastructure changes?

Yes, you can schedule regular cron runs that call listdeployments. LlamaIndex upserts only the modified deployment records into your vector database to keep the index fresh.

Q: How is my CoreWeave VPC data secured during LlamaIndex queries?

All responses from getvpc and querymetrics pass through TLS-encrypted channels directly to your local LlamaIndex instance. Vinkius acts as a zero-trust proxy and never logs the contents of your private network configurations.

Index your CoreWeave GPU states and logs into vector storage to query your live infrastructure with LlamaIndex.

Index live GPU cluster metrics for LlamaIndex RAG queries

The CoreWeave MCP Server converts live infrastructure states into queryable document indexes using `list_clusters` and `get_cluster`. Your LlamaIndex agent regularly pulls these configurations and embeds them into a vector store. When you ask about your current resource usage, the system performs a semantic search over these fresh documents. This gives you answers grounded in actual cluster states rather than outdated static files.

Troubleshoot deployments using indexed Loki logs

You can feed raw log data directly into your index using `query_logs` via this MCP Server. When an inference deployment fails, LlamaIndex pulls the latest log lines and matches them against historical failure patterns. The agent then runs `list_deployments` to verify which pods are affected. You get a detailed diagnosis and a recommended fix based on real-time log analysis.

Smart capacity claiming based on historical usage

This MCP Server allows your LlamaIndex pipeline to analyze past resource allocations using `list_capacity_claims`. The agent queries this historical index to determine the optimal GPU count for your next training run. Once the calculation is complete, the agent executes `create_capacity_claim` to reserve the exact physical hardware. This prevents over-provisioning and saves on idle GPU costs.

Setup guide

Set up CoreWeave (AI GPU Cloud) 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 CoreWeave (AI GPU Cloud) 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 CoreWeave (AI GPU Cloud) tools.",
)
response = await agent.run("List recent CoreWeave (AI GPU Cloud) data")
