gpu.nz GPU cloud

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.
