gpu.nz GPU cloud tools (16, 2 write)

write = sends, deletes, buys or posts
  • add_ssh_keyFree

    Adds an SSH public key (a line from a .pub file) to the account. Needs user:write.

  • create_instancewrite actionFree

    Rents the server of an offer and starts it with a template. Billing starts right away and runs every minute until you stop or destroy it. Confirm the price with the user first. Needs instances:write. The response has the instance id; poll get_instance until status is running (usually 1–5 minutes).

  • destroy_instancewrite actionFree

    Destroys a server and deletes its disk for good; billing stops completely. Irreversible: confirm with the user. Needs instances:write.

  • estimate_vramFree

    How much GPU memory an AI model needs (LLMs such as Qwen, DeepSeek, Llama, Gemma, GPT-OSS; image and video models such as FLUX, SDXL, Wan) at a given precision and context length, and which GPUs on gpu.nz fit it with their current price. Call without `model` to list the known models.

  • get_accountFree

    The signed-in account and its balance, hourly burn and runway. Needs a key with user:read and billing:read.

  • get_instanceFree

    Status, SSH command, app URLs (ComfyUI, Jupyter, chat…), price and cost so far of one server. The root password is left out unless include_password is true (your SSH keys are installed on every server).

  • get_instance_logsFree

    The last lines of a server's container log: boot progress, app start-up, errors. Needs instances:read.

  • get_offerFree

    Details and the current price of one offer by id (from search_offers).

  • list_gpu_modelsFree

    GPU models available on gpu.nz right now with VRAM, class and the cheapest hourly price per GPU. Use it to pick a gpu_slug for search_offers.

  • list_instancesFree

    Your rented servers with status, GPU, price and SSH command. Needs instances:read.

  • list_ssh_keysFree

    SSH public keys on the account; they are installed on new servers. Needs user:read.

  • list_templatesFree

    Ready environments a server can start with: ComfyUI, Stable Diffusion Forge, Ollama + Open WebUI, vLLM, Jupyter/PyTorch, Kohya, FluxGym, Unsloth, chats with preloaded models, plain Ubuntu + CUDA, or a custom Docker image. Pass `slug` as `template` to create_instance.

  • search_offersFree

    Search rentable GPU servers (offers) with live prices. Returns the cheapest matches first unless `order` says otherwise. Each result has an offer id for create_instance.

  • start_instanceFree

    Starts a stopped server again; GPU billing resumes. Confirm with the user. Needs instances:write.

  • stop_instanceFree

    Stops a running server: the GPU is released and billing drops to the disk only. Data on the disk is kept and the server can be started again (the GPU may then be taken by someone else; gpu.nz finds a replacement when it is). Needs instances:write.

  • topup_linkFree

    A link to the balance top-up page (SBP, crypto) for the user to open in a browser; payments never happen through the API. Optionally pre-fills the amount.

Install gpu.nz GPU cloud in Claude Code, Cursor or VS Code

Add to Cursor

What the publisher says

From the gpu.nz GPU cloud repository's README, as published. We do not edit it. Read it on GitHub

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 — claudedesktopconfig.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
