Overview

Description from the maker (original English)

Rent real GPUs from the terminal. Per-second billing, $0.50 minimum. stdio MCP server.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, SSE
  • Category: Other
  • You need to fill in: GPUSMARKET_API_KEY, Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: GPUSMARKET_API_KEY, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "gpusmarket": {
      "command": "npx",
      "args": [
        "-y",
        "gpusmarket"
      ],
      "env": {
        "GPUSMARKET_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport sse gpusmarket https://mcp.gpusmarket.com/sse --header 'Authorization: your-value'

Or run it on your computer

claude mcp add gpusmarket --env GPUSMARKET_API_KEY=your-value -- npx -y gpusmarket

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

      "url": "https://mcp.gpusmarket.com/sse",

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • GPUSMARKET_API_KEY secret required env
    GPUsMarket API key (gpu_...). Required: the MCP server exits without one. Get a key with 'gpusmarket signup' or from your dashboard.
  • Authorization secret HTTP header
    Bearer token using your GPUsMarket API key: 'Bearer gpu_...'. Optional: without one the server starts in onboarding mode and can self-signup via the gpusmarket_signup tool.

Common questions

Is Gpusmarket safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: GPUSMARKET_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.4.16) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

gpusmarket

Rent real GPUs from the terminal. Built for AI agents.

One command to sign up, one to rent, one to run inference. Per-second billing, no subscriptions, $0.50 minimum per rental. The CLI your coding agent can drive end-to-end: GPUsMarket.

`npm install` for GPUs. One command in, one command out.

Renting a GPU usually means a signup form, a quota request, a support ticket, and a $50 minimum — before you've run a single token. GPUsMarket collapses that to three commands: everything from consumer RTX 4090s to datacenter H100s and MI300Xs, rentable by the second. And it's built so your agent can sign up and rent by itself — no human, no browser, no dashboard.

Works with: Claude Code · Cursor · Cline · Windsurf · Aider · Codex · any MCP client

*Install to real inference in under a minute — watch the full-res demo.*

npm install -g gpusmarket

gpusmarket init

Quick start

# Create an account (returns your API key, auto-saved)

gpusmarket signup --email you@example.com --tenant my-agent

Find a GPU

gpusmarket search --gpu "RTX 4090"

Rent the cheapest match — returns an OpenAI/Ollama-compatible endpoint + key

gpusmarket rent --gpu "RTX 4090"

Run inference straight through your rental

gpusmarket chat "What is 2+2?" --model gemma3:4b

Stop when done — you pay for exactly the seconds you used

gpusmarket stop RENTAL-ID

Built for agents

Built so an agent can go from zero to running inference with no human in the loop — sign up, rent, infer, and stop, all from the terminal or over MCP. This CLI is designed to be driven by AI coding agents (Claude Code, Cursor, Cline, Windsurf, Codex, Copilot), not just humans.

  • `gpusmarket init` — in-terminal quickstart: detects your agent's config file, prints a ready-to-paste skill block, MCP setup, and next steps.
  • `gpusmarket init --agent-schema` — the full command contract as JSON: every command, every flag, plus the rules agents must follow. Load it into context and your agent never hallucinates a flag.
  • `--json` everywhere — every command has machine-readable output.
  • Zero dependencies — a single self-contained Node.js CLI. Nothing to audit but us.

Watch an agent drive it end-to-end (click for the full-res video):

*Claude Code searches, rents, runs inference, and stops the GPU — no human in the loop.*

MCP server

gpusmarket mcp-serve exposes 32 tools over stdio — search, rent, status, stop, chat, host, pools, the whole surface. Add it to Claude Code:

claude mcp add gpusmarket -- gpusmarket mcp-serve

…or drop it into any MCP client's .mcp.json. The MCP server runs outside your project directory, so pass your API key via the GPUSMARKET_API_KEY environment variable:

{

"mcpServers": { "gpusmarket": { "type": "stdio", "command": "gpusmarket", "args": ["mcp-serve"], "env": { "GPUSMARKET_API_KEY": "gpu_your_key_here" } } } }

No key yet? Run gpusmarket signup to provision one, or grab it from your dashboard.

Pool — one endpoint, several rentals behind it

Honest billing

  • Per-second billing. A 90-second experiment costs 90 seconds of GPU time.
  • A hold, not a charge. Renting places a pre-auth hold (default $10) — it's released in full when you stop. You are never charged the hold.
  • $0.50 minimum per rental. You pay per second for the compute you consume, subject to a $0.50 minimum charge per rental (disclosed when you rent). When you stop, your card is charged the exact usage cost, or the $0.50 minimum — whichever is greater.
  • Receipts for everything, with a full "where your money goes" breakdown.

Earn with your GPU

Your GPU earns nothing while it sits idle. List it in one command — the CLI auto-detects your hardware, prints your host key, and the listing goes live in minutes. You keep 90% of every rental, paid out to your Stripe account automatically. No port forwarding, no static IP, no open inbound ports.

Three ways to host (click any demo for the full-res video):

Mac (Apple Silicon)NVIDIA GPUDocker sidecar
gpusmarket host setupauto-detects CUDA + VRAMdocker compose up -d
gpusmarket host setup          # auto-detects your GPU, creates the listing

npx gpusmarket-host --key KEY # connect your machine — no port forwarding needed

Features

  • Search — filter the marketplace by GPU, price, or the exact model you need to run.
  • Rent — one command returns an OpenAI/Ollama-compatible endpoint + key, ready for inference.
  • Chat — stream inference straight through your rental, or pipe from stdin.
  • Pools — put several rentals behind one endpoint and load-balance across them.
  • Host — list your own GPU (Mac, NVIDIA, or Docker) and keep 90% of every rental.
  • Per-second billing — receipts for everything, $0.50 minimum per rental, no subscriptions.
  • MCP server — 32 tools over stdio for Claude Code, Cursor, Cline, Windsurf, any MCP client.
  • Agent-native — --json everywhere plus init --agent-schema so agents never guess a flag.

Why this exists

Renting a GPU should be as fast as npm install. Not a signup form, a quota request, a support ticket, and a $50 minimum. GPUsMarket is a marketplace where anyone can list an idle GPU and anyone — or any agent — can rent it by the second. This CLI is the agent-native front door to that marketplace. It's early and moving fast: if something's rough or missing, open an issue — we read every one.
