gpu.nz MCP server

Let Claude, Cursor, Codex and other AI agents rent cloud GPUs: search RTX 4090, A100, H100 and B200 servers with live prices, work out how much VRAM a model needs, launch ComfyUI, Ollama, vLLM or Jupyter, read the logs and stop the server when the job is done. Billed by the minute.

Connect

The server is hosted at https://gpu.nz/mcp — nothing to install. Browsing GPUs, prices and VRAM estimates works without a key; renting and managing servers needs an API key from gpu.nz/console/keys.

Claude Code

claude mcp add --transport http gpunz https://gpu.nz/mcp \
  --header "Authorization: Bearer gpz_…"

Cursor — ~/.cursor/mcp.json

{
  "mcpServers": {
    "gpunz": {
      "url": "https://gpu.nz/mcp",
      "headers": { "Authorization": "Bearer gpz_…" }
    }
  }
}

VS Code — .vscode/mcp.json (asks for the key once and keeps it in secret storage)

{
  "servers": {
    "gpunz": {
      "type": "http",
      "url": "https://gpu.nz/mcp",
      "headers": { "Authorization": "Bearer ${input:gpunz-key}" }
    }
  },
  "inputs": [{ "type": "promptString", "id": "gpunz-key", "description": "gpu.nz API key", "password": true }]
}

Codex CLI

export GPUNZ_API_KEY="gpz_…"
codex mcp add gpunz --url https://gpu.nz/mcp --bearer-token-env-var GPUNZ_API_KEY

Claude Desktop — claude_desktop_config.json, through mcp-remote

{
  "mcpServers": {
    "gpunz": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://gpu.nz/mcp", "--header", "Authorization:${GPUNZ_AUTH}"],
      "env": { "GPUNZ_AUTH": "Bearer gpz_…" }
    }
  }
}

On claude.ai you can add https://gpu.nz/mcp under Connectors without a key: search and estimates work.

Local stdio bridge

For clients that only start local servers, this repository is a small stdio bridge to the hosted server:

# Docker
docker run -i --rm -e GPUNZ_API_KEY="gpz_…" ghcr.io/gpunz/gpunz-mcp

# Node.js 18+, straight from GitHub
GPUNZ_API_KEY="gpz_…" npx -y github:gpunz/gpunz-mcp

Tools

Try asking

• How much VRAM does Qwen3.8 27B need with a 32k context, and where is it cheapest?

• Find the cheapest RTX 4090 with reliability above 0.98 and start ComfyUI on it with an 80 GB disk.

• Run GPT-OSS 120B on one H100 and give me the chat link when the server is ready.

• Show my servers and what they cost per hour; stop the ones I haven't touched since yesterday.

Money and safety

• The agent cannot spend more than your balance: top-ups happen in the browser only.

• create_instance, start_instance and destroy_instance are annotated as consequential, so clients ask you before running them.

• The root password stays out of tool output unless asked for explicitly; your SSH keys are installed on every server.

• The tools call the gpu.nz REST API with your key: its scopes, the rate limit (120 requests a minute per key) and the account's audit log apply.

По-русски

MCP-сервер gpu.nz подключает аренду видеокарт к ИИ-агентам: Claude, Cursor, Codex и другим. Агент сам найдёт подходящую видеокарту, посчитает видеопамять для модели, арендует сервер с ComfyUI, Ollama или vLLM, прочитает логи и остановит сервер. Адрес: https://gpu.nz/mcp, оплата поминутная, в рублях через СБП или криптой. Документация: gpu.nz/docs/mcp.
